  SCOWL is derived from many sources, most of which are in the Public Domain.
  The primary source of words comes from 12dicts and ENABLE2K (both Public
  Domain, Alan Beale).

The list is size 60 (the default spell-checker size) with US and British
spellings, so none of the Australian or UKACD (size > 80) terms apply.

How scowl-v2-60-en_US-en_GB.txt was generated (Python 3.12, PYTHONUTF8=1):

  python combine.py create-db scowl.db
  python scowl word-list 60 A,B,Z 1 --regions US,GB --categories= \
      --wo-poses abbr,pre,suf,s \
      --wo-usage-notes offensive-1,offensive-2,vulgar-1 \
      --deaccent --dot True > scowl-v2-60-en_US-en_GB.txt

  60                  SCOWL size 60
  A,B,Z 1             American, British (-ise) and British (-ize) spellings, variant level 1
  --regions US,GB     no Canadian/Australian-only words
  --categories=       no Roman numerals, no programmer slang ("hacker" category)
  --wo-poses          no abbreviations, prefixes, suffixes, contractions
  --wo-usage-notes    removes words SCOWL marks as offensive-1, offensive-2
                      (racial slurs) and vulgar-1 (swear words); 62 lines.
                      SCOWL notes that this marking only covers the worst
                      offenders.
  --deaccent          accents removed (cafe instead of café)
  --dot True          abbreviations keep their trailing dot and are therefore
                      dropped by the build step below

scripts/build-wordlist.mjs (language "en") then keeps only entries that consist
of lowercase letters a-z with 2-20 letters. This removes proper nouns (capital
letter), possessives and other apostrophe forms, dotted abbreviations and
hyphenated words. Inflected forms (plurals, verb forms) are included.
