shortened form like “don't”
A short form of a word or words, made by leaving out letters or sounds, often written with an apostrophe, like “I'm” for “I am”.
用法パターン：
the contraction of [word/phrase]
よくある間違い：
Learners often confuse contractions with abbreviations (e.g., thinking "Dr." is a contraction). Another frequent mistake is mixing up similar contractions and possessives, such as "it's" (it is/has) vs. "its" (possessive), or "you're" (you are) vs. "your" (possessive). Some learners also think contractions are always wrong in writing, but they are normal in most informal and semi-formal texts.
類義語
short form (More informal and descriptive; less technical than “contraction”.)
|

対義語
full form (Refers to the complete, unshortened version of a word or phrase, such as “do not” instead of “don't”.)

tightening of a muscle
A strong tightening of a muscle that makes it shorter, which can move part of the body or cause pain.
用法パターン：
a contraction of [muscle/body part]
よくある間違い：
Learners sometimes confuse "contraction" with "cramp" or "spasm." A cramp is a type of painful, often sudden contraction, but not every contraction is a cramp. Also, some learners use "contraction" to mean any kind of pain, which is too broad.
類義語
tightening (More general word for becoming tight; less specifically medical or muscular.)
|
spasm (Suggests a sudden, often painful or uncontrolled contraction, usually seen as more severe or abnormal.)
対義語
relaxation (Describes a muscle returning to a loose, resting state, the opposite of tightening or contracting.)

painful tightening in labor
A strong pain when the womb muscles tighten again and again to help the baby come out during birth.
用法パターン：
have contractions
よくある間違い：
Learners may not realize that, in the context of pregnancy, "contractions" usually refers specifically to labor pains in the uterus, not just any muscle pain. Some also confuse "contractions" with "conception" or "contraception" because the words look similar but have very different meanings.
類義語
labor pain (Focuses on the feeling of pain rather than the muscle action itself, but often used in the same context.)
対義語
relaxation (Refers to the period when the uterus muscles are not tightening between contractions.)

4
process of becoming smaller
The process of something becoming smaller or shorter, for example when it gets cold or loses water.
用法パターン：
a contraction in [size/length/amount]
よくある間違い：
Learners may misunderstand this sense and think it only refers to language (word contractions), not realizing it is also a common scientific term for shrinking in size. Another confusion is using "contraction" when they simply mean "contract" as a verb, for example saying "the metal has a contraction" instead of "the metal contracts."
類義語
shrinkage (Everyday word that often refers to things getting smaller, especially clothes or materials, sometimes more informal.)
|
reduction (Very general word for becoming less or smaller; does not always imply physical size.)
対義語
expansion (Describes something becoming larger in size or volume, often due to heating, the opposite of contraction in physics.)
|
growth (General increase in size or amount; broader than “expansion” but opposite to the idea of becoming smaller.)
コロケーション

|contraction and expansion
|contraction of metal

5
period of economic decline
A time when a country’s economy is doing less business, making fewer goods, and often losing jobs.
用法パターン：
a contraction in [the economy/demand/output]
よくある間違い：
Learners may confuse "contraction" with "contract" (the legal document) in economic news. Some also think "contraction" is always as strong as a "recession" or a "crisis"; in fact, it can describe any period of negative or slower growth, which may be mild.
類義語
downturn (Common business term for a general worsening of economic conditions; slightly less technical than “contraction”.)
|
recession (A more specific economic term, often defined by at least two quarters of negative growth; not every contraction is officially a recession.)
対義語
boom (Colloquial term for fast or strong economic growth, clearly opposite in feeling to a contraction.)
コロケーション
