- Enum Constant Detail
  - CC
```
public static final PennTreebankPOS CC
```
    Coordinating conjunction. This category includes and, but, nor, or, yet (as in Yet it's cheap, cheap yet good), as well as the mathematical operators plus, minus, less, times (in the sense of "multiplied by") and over (in the sense of "divided by"), when they are spelled out. FOR in the sense of "because" is a coordinating conjunction (CC) rather than a subordinating conjunction (IN) -
    He asked to be transferred, for/CC he was unhappy.
    SO in the sense of "so that," on the other hand, is a subordinating conjunction (IN).
  - CD
```
public static final PennTreebankPOS CD
```
    Cardinal number.
  - DT
```
public static final PennTreebankPOS DT
```
    Determiner. This category includes the articles a(n), every, no and the, the indefinite determiners another, any and some, each, either (as in either way), neither (as in neither decision), that, these, this and those, and instances of all and both when they do not precede a determiner or possessive pronoun (as in all roads or both times). (Instances of all or both that do precede a determiner or possessive pronoun are tagged as predeterminers (PDT).) Since any noun phrase can contain at most one determiner, the fact that such can occur together with a determiner (as in the only such case) means that it should be tagged as an adjective (JJ), unless it precedes a determiner, as in such a good time, in which case it is a predeterminer (PDT).
  - EX
```
public static final PennTreebankPOS EX
```
    Existential there. Existential there is the unstressed there that triggers inversion of the inflected verb and the logical subject of a sentence. Examples:
    There/EX was a party in progress.
    There/EX ensued a melee.
  - FW
```
public static final PennTreebankPOS FW
```
    Foreign word.
  - IN
```
public static final PennTreebankPOS IN
```
    Preposition or subordinating conjunction. We make no explicit distinction between prepositions and subordinating conjunctions. (The distinction is not lost, however -- a preposition is an IN that precedes a noun phrase or a prepositional phrase, and a subordinate conjunction is an IN that precedes a clause.) The preposition to has its own special tag TO.
  - JJ
```
public static final PennTreebankPOS JJ
```
    Adjective. Hypenated compounds that are used as modifiers, like happy-go-lucky, one-of-a-kind and run-of-the-mill, are tagged as JJ. Ordinal numbers are tagged as JJ, as are compounds of the form n-th x-est, like fourth-largest.
  - JJR
```
public static final PennTreebankPOS JJR
```
    Adjective, comparative. Adjectives with the comparative ending -er and a comparative meaning. Adjectives with a comparative meaning but without the comparative ending -er, like superior, should simply be tagged as JJ. Adjectives with the ending -er but without a strictly comparative meaning, like further in further details, should also simply be tagged as JJ.
  - JJS
```
public static final PennTreebankPOS JJS
```
    Adjective, superlative. Adjectives with the superlative ending -est. Adjectives with a superlative meaning but without the superlative ending -est, like first, last or unsurpassed, should simply be tagged as JJ.
  - LS
```
public static final PennTreebankPOS LS
```
    List item marker. This category includes letters and numerals when they are used to identify items in a list.
  - MD
```
public static final PennTreebankPOS MD
```
    Modal verb. This category includes all verbs that don't take an -s ending in the third person singular present: can, could, (dare), may, might, must, ought, shall, should, will, would.
  - NN
```
public static final PennTreebankPOS NN
```
    Noun, singular or mass.
  - NNS
```
public static final PennTreebankPOS NNS
```
    Noun, plural.
  - NNP
```
public static final PennTreebankPOS NNP
```
    Proper noun, singular.
  - NNPS
```
public static final PennTreebankPOS NNPS
```
    Proper noun, plural.
  - PDT
```
public static final PennTreebankPOS PDT
```
    Predeterminer. This category includes the following determinerlike elements when they precede an article or possessive pronoun. Examples:
    all/PDT his marbles
    nary/PDT a soul
    both/PDT the girls
    quite/PDT a mess
    half/PDT his time
    rather/PDT a nuisance
    many/PDT a moon
    such/PDT a good time
  - POS
```
public static final PennTreebankPOS POS
```
    Possessive ending. The possessive ending on nouns ending in 's or ' is split off by the tagging algorithm and tagged as if it were a separate word. Examples:
    JohnINP 's/POS idea
    the parents/NNS '/POS distress
  - PRP
```
public static final PennTreebankPOS PRP
```
    Personal pronoun. This category includes the personal pronouns proper, without regard for case distinctions (I, me, you, he, him, etc.), the reflexive pronouns ending in -selfor -selves, and the nominal possessive pronouns mine, yours, his, hers, ours and theirs. The adjectival possessive forms my, your, his, her, its, our and their, on the other hand, are tagged PP$.
  - PRP$
```
public static final PennTreebankPOS PRP$
```
    Possessive pronoun. This category includes the adjectival possessive forms my, your, his, her, ids, one's, our and their. The nominal possessive pronouns mine, yours, his, hers, ours and theirs are tagged as personal pronouns (PP).
  - RB
```
public static final PennTreebankPOS RB
```
    Adverb. This category includes most words that end in -ly as well as degree words like quite, too and very, posthead modifiers like enough and indeed (as in good enough, very well indeeed), and negative markers like not, n't, and never.
  - RBR
```
public static final PennTreebankPOS RBR
```
    Adverb, comparative. Adverbs with the comparative ending -er but without a strictly comparative meaning, like later in "We can always come by later", should simply be tagged as RB.
  - RBS
```
public static final PennTreebankPOS RBS
```
    Adverb, superlative.
  - RP
```
public static final PennTreebankPOS RP
```
    Particle. This category includes a number of mostly monosyllabic words that also double as directional adverbs and prepositions.
  - SYM
```
public static final PennTreebankPOS SYM
```
    Symbol. This includes / [ = *, #, etc. This tag should be used for mathematical, scientific and technical symbols or expressions that aren't words of English. It should not used for any and all technical expressions. For instance, the names of chemicals, units of measurements (including abbreviations thereof) and the like should be tagged as nouns.
  - TO
```
public static final PennTreebankPOS TO
```
    to.
  - UH
```
public static final PennTreebankPOS UH
```

public final boolean open

    True if the POS is a open class.
- Method Detail
  - values
```
public static PennTreebankPOS[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (PennTreebankPOS c : PennTreebankPOS.values())
    System.out.println(c);
```
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static PennTreebankPOS valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    name - the name of the enum constant to be returned.
    
    Returns:
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getValue
```
public static PennTreebankPOS getValue(String value)
```
    Returns an enum value from a string. Note that valueOf cannot be overridden so we have to use this workaround for converting custom strings to enum values without using valueOf method.
