Hi Florent,

> vana.m gacchanto ekaaya kaasuya.m pati.
> [in] that / [in] village / [of] living / [of] people / one / axe /
> took / [to] forest / going / a / [in] pit / fell
> In that village where people are living, one having taken an axe fell
> in a pit while going to the forest.
The feminine locative singular can be either ekaaya or ekaaya.m. Of
course if one is composing in Pali then ekaaya.m will be better since
it is unambiguous.
