How to say "maternal" in Japanese
Choosing the right word
- 種違いたねちがいno-adjectiveRefers to a half-sibling related through the mother but with a different father. This is really about sibling relationships, not motherly feeling, so it is seldom the word you want for 'maternal' in the usual sense.
- 種変わりたねがわりno-adjectiveLike 種違い, it denotes a half-sibling with the same mother and a different father. It does not express the motherly sense of 'maternal', and as a marginal match it is rarely the word you want.
- 母親らしいははおやらしいi-adjectiveDescribes a person or behavior that seems like a good mother: warm, caring, protective. Use it for the figurative sense of 'maternal', as in a maternal smile or instinct.
- 母性的ぼせいてきna-adjectiveAn adjective for qualities resembling those of a mother, such as warmth or a nurturing instinct. Suitable for the figurative 'maternal' sense, much like 母親らしい but slightly more formal in feel as a derived adjective.
- 母方ははかたno-adjectiveThe default choice for 'maternal' in family terms: it marks relatives as belonging to the mother's side, as in a maternal grandfather, uncle, or grandmother.
For relatives on the mother's side, use 母方; for a motherly quality or manner, 「母親らしい」 or 母性的; 「種違い」 and 「種変わり」 concern half-siblings sharing a mother, not the motherly sense.
