Gnomish

irtha-

verb. to peck

A verb appearing as G. {irta- >>} irtha- “peck” in the Gnomish Lexicon of the 1910s (GL/52), probably based on the early root ᴱ√ᴵRTYᴵR “peck, prick” from the contemporaneous Qenya Lexicon (QL/43).

Neo-Sindarin: I would retain this verb as ᴺS. irtha- “to peck” based on the Neo-Root ᴺ√IRIT “peck, prick”.
