Select the most appropriate synonym of the given word. Stationary

Correct — C. Stationary, with an -ary ending, is an adjective meaning not moving, fixed in one place.

Still carries exactly that sense — a still vehicle, a still figure — so it is the closest one-word match: option (c).

The word to keep apart is stationery, with an -ery ending, which is the noun for paper, pens and envelopes and says nothing about movement.

Why the others are wrong

• (a)
  Portable — Portable means able to be carried from place to place, so it is built on movement. That inverts the sense of stationary instead of matching it.
• (b)
  Swindle — Swindle is a verb meaning to cheat somebody out of money. It is not even the same part of speech as the adjective stationary, and shares none of its sense.
• (d)
  Motile — Motile means capable of moving on its own, a word biology uses of cells and organisms. It sits at the far end from stationary, so it is an antonym.

A synonym item is decided by part of speech first, sense second. Stationary is an adjective about position, so the answer must be an adjective about position.

That single filter removes swindle, a verb, before you weigh any meaning at all.

What is left splits into movement words and stillness words. Portable and motile both encode movement, and only still encodes its absence — which is what stationary means.

Key facts

• Stationary, spelt with -ary, is an adjective meaning not moving.
• Stationery, spelt with -ery, is the noun for writing materials such as paper and pens.
• Motile means capable of independent movement, and is used mainly of cells, spores and organisms.
• Still, used as an adjective, means without motion, which is the sense stationary carries.

Common traps

• Reading the stem as stationery and hunting for a paper-and-pens word.
• Choosing motile because it looks technical, when it names the opposite property.
• Treating portable as neutral movement vocabulary rather than the antonym it is.
