How to say "mould" in Japanese

Choosing the right word
  • カビCommon
    nounMould in the biological sense: the fuzzy growth that appears on food, walls, or anything damp, covering mildew as well. It is never a mould for shaping material.
    Mold grew on the boots.
  • 鋳型いがたCommon
    nounA mould used in casting: the hollow form into which molten metal is poured. It can also mean a template, a pattern to copy.
    人間にんげんは鋳型いがたに入いれて作つくるわけにはいかない。↗
    A man cannot be made in a mold.
  • 形作るかたちづくるCommon
    godan verb, transitive verbThe verb 'to mould': to shape or form something, giving it its shape or character, of objects and abstract things alike. Use it whenever moulding is an action rather than a thing.
    彼かれは粘土ねんどで像ぞうを形作かたちづくった。↗
    He shaped the statue from clay.
  • 型枠かたわくCommon
    nounFormwork or shuttering: the mould erected on a building site to hold wet concrete in shape until it sets. Outside construction this is not the word you want for 'mould'.
  • 型かたJLPT N3approx.Common
    nounThe general word for a mould as a shaping form, and by extension a model, pattern, or type, including figurative uses; when no casting or construction term fits, this is the word.
    その像ぞうは型かたに入いれられて作つくられた。↗
    The statue was cast in a mold.

Take 「カビ」 for the fungus, 鋳型 for casting moulds, 型枠 for formwork, 型 for moulds and patterns in general, and 「形作る」 when 'mould' is a verb meaning to shape.
