delatar
/delaˈtaɾ/ · B2 · verb
give away, betray, belie, reveal
🐀 delatar = de- + lata (tin can): spilling what's inside the can
Sounds like de-LA-tar: someone who talks. Link it to a rat who spills secrets: a rat who delatar-s tells the cops. In Spanish the 'rat' idiom exists too (rat out), so the English meaning is easy to anchor to the sound 'de-la-TAR': he tells, you are tarred.
