Question

Irish: Building/Making a Birdhouse
Focloir.ie says that teachín éan means "birdhouse". Is that correct and if so, what are the plural and the genitive forms?

Also, does "teachín éan a dhéanamh" mean to build/male a birdhouse?

Answer

"Teachín éan a dhéanamh/a thógáil" is correct.

All words ending in -ín (which are always masculine) form the plural with -í, and the genitive is the same as the nominative (4th declension), so nom./gen. pl. teachíní éan; nom./gen. sg. teachín éan.

Answer

The dictionary says:
teachín: gs. teachín npl. teachíní gpl.teachíní

By the way,
éan gs. éin npl. éin gpl. éan

Anyway, let's wait for the experts' verdict.
