Might they be used regularly in Ulmeni? (3)
I believe the answer is:
lei
'might they be' is the definition.
The definition and answer are not the same part of speech.
'regularly in ulmeni?' is the wordplay.
'regularly in' means one should take alternating letters.
The alternate letters of 'ulmeni' are 'LEI'.
'used' acts as a link.
(Other definitions for lei that I've seen before include "colourful flower arrangement" , "Flower garland of Hawaii" , "Hawaiian wreath" , "cash for Romanians" , "Hawaiian necklace of flowers" .)
