Bingo codes (Blanks not included)
The 2-9 letter word lists do not include inflections of shorter words. This does not apply
to the TWL3-only bingos. Parts of speech, but not definitions are included. Words that have
no difference between the plural and singular of nouns are marked as "n/pl". Inflections of the
main word are only included if they do not appear as a separate entry elsewhere. Because of that,
the word BAD does not include WORSE and WORST because they appear as nouns later on. Likewise,
GOOD is only included as a noun because the adjectival forms of BETTER and BEST appear as verbs!
If two words have the same inflections, such as JOKEY and JOKY (both having JOKIER and JOKIEST),
only JOKY has those listed since they appear first if you're studying by word length.
The rack probability numbers are calculated by multiplying each letter's distribution value
(12 for E, 8 for O, etc.). If there are two E's, it's calculated as 12x11 / 1x2 = 66. If there
are three E's, it's calculated as 12x11x10 / 1x2x3 = 220. To simplify things a bit, any word that
is impossible to play without blanks has a word probability of 0.
