Prepositions after verbs

Subdivide into, by, for or in?

Subdivide is most commonly followed by into for parts or sections. By can describe the method of division.

Quick answer

Which preposition goes with subdivide?

Use subdivide into to name the smaller parts created by the division. Use subdivide by to explain the basis or method of division. Subdivide for is uncommon after the verb itself, and subdivide in is usually part of a separate place phrase rather than a fixed verb pattern.
