I just rediscovered the colloquial expression "latch on to [something]" online and would like to know the story to its meaning of "obtain, get", which is presented by CD as AE and CE.
What I wish you could tell is if this idiom is appropriate for any sense of "obtain, get hold of" (i.e. come into possession, get, acquire, procure, find, as through effort or request). Or is it only suitable for specific contexts, and for certain registers but the most formal ones?
