## Lexicon Entries
The lexicon `english.csv` uses a variation of the comma separated value (CSV)
format. Each line contains one **lexeme**:
* Value 1: **lemma** : **word class** {.**attributes**}
* Values 2+: **irregular inflected forms**
Example:
```
go:V,goes,going,went,gone
```
### Lemma (Base Word)
The base or canonical form of a word, usually in all lowercase.
### Word Class
Codes for one of nine basic word classes:
| `A` | Adjective |
| `Av` | Adverb |
| `C` | Conjunction |
| `D` | Determiner |
| `I` | Interjection |
| `N` | Noun |
| `P` | Preposition |
| `Pn` | Pronoun |
| `V` | Verb |
### Attributes
If any attributes are provided, they are preceded by a dot `.`:
| `a` | Auxiliary verb | _cannot_
| `c` | Comparative inflected forms | _big_ `=>` _bigger_ `=>` _biggest_
| `n` | Proper (name) noun | _Monday_
| `p` | Plurale Tantum | _pants_, _scissors_
| `s` | Singulare Tantum | _dust_, _information_
| `t` | Transitive verb or preposition |
| `z` | Alternate `-ize`, etc. forms | _realize_ `=>` _realise_
### Inflected Forms
Forms are modifications of the **lemma**, indicating tense, number, etc.
These forms can be **regular** or **irregular**. If no irregular forms are
provided, regular forms will be automatically generated for these four word
classes:
- **Adjective**: Comparative (*er*), Superlative (*est*)
- **Noun**: Plural (*s*)
- **Pronoun**: Plural (*s*)
- **Verb**: Present tense (*s*), Present participle (*ing*),
Past tense (*ed*)
The suffixes are attached to lemmas based on special rules.
Irregular forms can be abbreviated with a hyphen (\-) at the beginning. This
includes the lemma, trimmed to the first letter after the hyphen.
For example:
```
alumnus:N,-ni
```
### Special Characters
Some characters create alternate forms when included in a *lemma*:
| `à` | `a` |
| `â` | `a` |
| `é` | `e` |
| `è` | `e` |
| `ê` | `e` |
| `ï` | `i` |
| `ñ` | `n` |
| `ü` | `ue`, `u` |
| `æ` | `ae`, `e` |
| `œ` | `oe`, `e` |
| `ç` | `c` |
