There are utilities that convert the lexicon entries from a format that is easy for the computer to read to one that is easy for a human to read, and back again. The human-readable format is called a dump-format, the other a lex-format.
Currently there are two programs that deal directly with the lexicon.
ltod (lex to dump) reads in a lexicon and prints out selected
items in the long (dump) format. If the word has multiple entries in the
lexicon (for example 'do', which is among other things a possessive adjective
and a preposition) then all are printed. Also, if the word has irregular
forms, all the forms will be printed.
to see a sample printout.
dtol (dump to lex) reads the long dump format and turns
it info the compact format used by the programs. By filling in the
form below, you can add a word to the lexicon - then use
to check that the info is correct, and
look at the inflectional pattern.
