baby’s bed with high sides
A small bed for a baby with high sides, so the baby cannot fall out. In American English this is called a “crib”.
用法パターン：
put [a baby] in a cot
よくある間違い：
Learners often confuse “cot” and “crib.” In British and most international English, “cot” is the normal word; in American English, “crib” is used instead. Many learners also mix up the spelling and pronunciation of “cot” with “coat” or “cut.” Remember that “cot” has the same vowel as “not” in most accents.
類義語
crib (The standard American English word for a baby’s bed with high sides; in British and many other varieties, “cot” is preferred.)
|
baby bed (A more descriptive phrase, sometimes used when speaking to learners or in international English.)

narrow portable bed for one
A small, simple bed that is easy to move, often used for camping, extra guests, or in hospitals.
用法パターン：
sleep on a cot
よくある間違い：
Learners sometimes use only “small bed” instead of “cot,” or confuse a “cot” with a “sofa bed.” A cot is usually narrow, simple, and easy to move; a sofa bed is a sofa that opens into a larger bed. Also, do not confuse this sense with the baby’s “cot” (crib). Context (baby vs adult, camping vs nursery) usually makes the meaning clear.
類義語
camp bed (Common in British and international English, especially for camping; “cot” is more general and also used for spare beds indoors.)
|
folding bed (Emphasizes that the bed can be folded; can be slightly larger or more solid than a simple cot.)

simple framed bed (South Asia)
In Indian and some other South Asian English, a basic bed with a frame, often with ropes or a flat board, used every day in the home.
用法パターン：
sit on the cot
よくある間違い：
Learners outside South Asia may not realize that in Indian and some South Asian English, “cot” can mean an ordinary bed, not only a baby’s bed or a camping bed. Context (village house, veranda, rope, iron frame) usually shows this regional sense.
類義語
charpoy (A traditional woven rope bed in South Asia; more specific and culturally marked than the general word “cot.”)
|
bed frame (A more technical term; “cot” in South Asia refers to the complete everyday bed, not only the frame.)

trigonometric function cotangent
In mathematics, “cot” is short for the function “cotangent.” For an angle, cot(angle) = cos(angle) ÷ sin(angle).
用法パターン：
cot [angle]
よくある間違い：
Learners sometimes confuse “cot” with “cos” or “tan,” or think it is an unrelated word. Remember that “cot” in formulas is short for “cotangent,” and cot x = cos x ÷ sin x = 1 ÷ tan x. Also, this mathematical “cot” is completely different from the bed meanings in everyday English.

cotangent (The full, non-abbreviated name of the same trigonometric function; used in explanations and formal writing.)
