i made a regex for determining if someone is a lily: /lill?(y|i(e$)?)(th|an(ne|a)?)?/gmi

explanation:

• match lil

• maybe match another l

• match y or i

• if matched i, match e if it's at the end of the string

• maybe match th, or an

• if matched an, maybe match ne or a

EDIT: more efficient version by @domi@donotsta.re (src: https://donotsta.re/objects/02824ead-e4a6-4aef-a129-827aab59d3ea) /lil*?[yi]([ea]|th|an(ne|a)?)?/gmi

explanation:

• match li, then l again once or twice

• match y or i

• maybe match one of:

  • e or a

  • th

  • an, then ne or a
