लागणे(lAgaNe) is one verb. But it has many different meanings !!
Generally, sentence structure will follow this pattern.

Form of subject with preposition "to" object
form of लागणे(lAgaNe) as per object
मला (malA)बादली (bAdalI )
लागते (lAgate)

1) To Need

There is a subtle difference in “To need” and “To want”. A need is something you have to have, something you can’t do without. A good example is a food.  A want is something you would like to have. It is not absolutely necessary, but it would be a good thing to have. A good example is music.

So to indicate “To need” in colloquial Marathi, we use verb लागणे(lAgaNe).
Sentence structure is same as above

I will need bucket -> मला बादली लागेल (malA bAdalI lAgel)
