You use all-round when a person — or sometimes a thing — is good in many different ways, not just one. An all-round student is not only strong in maths, but in sport, music, talking with people: the whole picture.

when a person當一個人—— or sometimes a thing或有時候一個東西—— in many different ways在很多不同方面 is good都不錯、 not just one不只一項的時候， You use你就用 all-round。 An all-round student全方位的學生 not only strong in maths不是只有數學強， but還有 in sport運動、 music音樂、 talking with people跟人相處這些也行： the whole picture是整個面向。

It is mainly British; American English prefers all-around, with the same idea. People also put it in front of a skill or a quality: all-round ability, all-round fitness. It feels everyday, not fancy, and it almost always sits before a noun.

It它 is mainly British主要是英式用法； American English美式英文 prefers偏好 all-around， with the same idea意思相同。 People人們 also也 put it把它放在 in front of a skill or a quality技能或特質前面： all-round ability全面的能力、 all-round fitness全面的體能。 It它 feels感覺 everyday很日常、 not fancy不花俏， and it而且它 almost always幾乎總是 sits before a noun放在名詞前面。

Though actually, the older meaning was closer to “everywhere, on every side,” and that still lives in the two-word phrase all round (“drinks all round”). The hyphenated all-round here is the later sense: versatile, good at many things.

Though actually不過其實， the older meaning較早的意思 was closer to比較接近 “everywhere, on every side,”「到處、四面八方」， and that still lives而那個意思還活在 in the two-word phrase分成兩個字的片語 all round裡 (“drinks all round”「在場每人一杯」)。 The hyphenated帶連字號的 all-round here在這裡 is the later sense是比較晚出現的意思： versatile多面向、 good at many things很多事都行。
