the inflector helper works really well but I came across a few words which need inclusion in the singular-rules. since this is a system file i felt it better not to touch it myself.
aword..................inflector_singular.............shouldbe
carta....................cartum.............................carta (as in magna carta)
christmas............christma...........................christmas
clothes................clothe...............................clothes (no singular)
cookies...............cooky...............................cookie
gloves.................glofe................................glove
kiddies................kiddy...............................kiddie (maybe?)
leaves.................leafe...............................leaf
sleeves...............sleefe..............................sleeve
india...................indium.............................india
it got the other 800+ words correct which is very impressive
many thanks for a great system
