Emotional and mental adulthood
The state of thinking and acting in a calm, responsible, adult way.
用法パターン：
[someone]'s maturity
よくある間違い：
Learners sometimes think 'maturity' only means age. In everyday English it often means emotional or mental development, so a young person can have 'a lot of maturity'. Another mistake is using it as an adjective, e.g. *'He is very maturity'* instead of 'He is very mature' or 'He has a lot of maturity.'
類義語
responsibility (Focuses more on doing what you should do, not on the whole inner emotional development.)
|
adulthood (Usually means being an adult by age; it does not always include the idea of wise or calm behavior.)
対義語
immaturity (Direct opposite; behaving in a childish or irresponsible way.)
|
childishness (Suggests silly, overly childlike behavior rather than balanced adult behavior.)

Due date of a financial product
The final date when a loan, bond, or similar product must be paid back.
用法パターン：

よくある間違い：

類義語
due date (A more general term for when something should be finished or paid; not limited to financial products.)

Full development of a system or idea
A late, fully developed stage of growth for a system, industry, or idea.

類義語
full development (Very close in meaning but more general and less commonly used in technical discussions of systems or markets.)

Biological ability to reproduce
The time in life when a person or animal can have babies.
用法パターン：

類義語
puberty (Common word for humans; includes physical and hormonal changes, while 'sexual maturity' focuses on the ability to reproduce.)
対義語
prepuberty (Refers to the period before puberty, when reproduction is not yet possible.)
