Do you see what this word is?
Maybe preposition ל prefixed to a plural feminine noun?
Maybe preposition ל + an Infinitive construct?
In a general way, both are possible.
We know indeed the feminine noun שָׁנָה, year, and we know too verb שָׁנָה, to change.
If our word is the first, then it would mean to years; if it is the second then it would be to change.
