LUNO

This is an archaic Tagalog word.

luno
weak, weary


lunong katawan
weak body


lunong isip
weary mind


lunong-luno
very exhausted



The more common Tagalog word for 'weakness' is hina. For 'weak' it's mahina.



An even more obscure definition for the word luno is to 'molt' or shed one's skin.
