tigrät- means ‘to make clatter or rattle, cause to produce a clattering sound’. The form in Irk Bitig 50 has traditionally been interpreted as ‘make the horse break wind’, but this interpretation is disputed. Erdal notes that the runiform spelling permits both tigrät- and tigirt- and interprets either form as ‘to cause someone or something to produce a certain, perhaps clattering, sound’. Old Uyghur tigrät- likewise has the broader meanings ‘cause, make resound or clatter, shake’. The specific meaning ‘make a horse break wind’ should therefore be treated only as a possible contextual interpretation.

Closely comparable verbs survive in several modern Turkic languages, although they cannot safely be treated as direct descendants of the exact stem tigrä-. Compare Turkish tıkırda- and Uzbek tiqirla- ‘to make a clicking or clattering sound’. Particularly noteworthy is Chuvash tĕkĕrtet: Ashmarin records it both of a ticking or rattling watch and with the meaning ‘to walk unevenly (of a child)’, while tĕkĕr-tĕkĕr is likewise used of a small child beginning to walk. The semantic agreement with Kāšġarī’s oğlan tigrädi ‘the boy toddled’ is striking. Morphologically, however, Chuvash tĕkĕrtet is tĕkĕr + -tet, the latter being a Chuvash suffix forming verbs from imitative bases; it is therefore a possible parallel derivative from the same or a similar expressive base, not a secure direct reflex of tigrä-.
