领带(lǐng dài) - tie, necktie in Mandarin

领带 (lǐngdài) is a necktie: 领 (lǐng) means collar and 带 (dài) means a strip or band, so the compound is literally a "collar band", a fair description of what it is.

The verb you need is 打 (dǎ), which usually means to hit or to play but here means to tie: 打领带 (dǎ lǐngdài), to tie a tie, or 打一条领带 (dǎ yì tiáo lǐngdài) for a specific one. Do not reach for 穿 (chuān), wear, the way you would with a shirt or jacket.

The measure word is 条 (tiáo), the measure word for long thin things: 一条领带 (yì tiáo lǐngdài), one tie. It goes with 衬衣 (chènyī), shirt, and 西装 (xīzhuāng), suit, as part of formal dress.
