made of different parts combined
Made from different parts or materials that are put together as one thing.
用法パターン：
a composite [noun]
よくある間違い：
Learners sometimes use "composite" when they only mean "many" or "complex". "Composite" should describe something physically or clearly made from different parts or materials, not just something complicated. For example, "a composite plan" is unusual unless the plan is explicitly built from separate plans.
類義語
combined (General word; does not always imply different types of materials or elements.)

mixed (More informal; often suggests a less structured blend than "composite".)
|
compound (More formal and technical; often used in chemistry and grammar.)
対義語
single (Emphasizes that something is made from only one piece or element.)
|
pure (Suggests only one substance without other materials mixed in.)

thing made from combined parts
A thing that is made from different parts or pieces put together.
用法パターン：
a composite of [things]

類義語
combination (Very general; does not always imply a single new whole in the same way as "composite".)
|
blend (More informal and often used for tastes, styles, or qualities.)
|
mixture (Common and informal; can sound less structured than "composite".)
対義語
component (A part of a whole, rather than the whole made from many parts.)

engineered material from several substances
A man-made material that is made from two or more different materials joined together to make something stronger or better.
用法パターン：
a composite [used for/with] [purpose]
よくある間違い：
Learners may think "composite" is only an adjective and say "a composite material" when an engineer might simply say "a composite". Both are acceptable, but in technical writing the short noun form is very common.
類義語
composite material (More explicit phrase; often preferred in teaching or non-specialist contexts.)
対義語
monolithic material (Used in engineering for materials made from a single substance, not layered or combined.)

of a number: not prime
Used about a whole number that is not prime because it can be divided exactly by smaller whole numbers, not only by 1 and itself.
用法パターン：

よくある間違い：
Learners sometimes mix up "prime" and "composite" or think that 1 is composite. In standard mathematics, 1 is neither prime nor composite.
類義語
non-prime (Clear but less common; usually used only in explanations or teaching.)
対義語
prime (Standard mathematical opposite: a number with no positive divisors other than 1 and itself.)

用法パターン：
[number] is a composite

combine images into one
To put two or more pictures or video parts together to make one final image or video.
用法パターン：
to composite [image/element] into/over [background]
