SFのThe Martian by Andy Weirを読んでいます。
Now fatigued, the astronaut stood with arms akimbo, looking up at the sleek lines of the engineering marvel before him.
"akimbo" は英語らしくないので以前に取り上げた気がしますが、記録にありません。そこで復習です。
・Oxford English Dictionary: With hands on the hips and elbows turned outward.: 'she stood with arms akimbo, frowning at the small boy’
・Cambridge English Dictionary: If a person's arms are akimbo, they are bent at the elbows (= the middle part of the arms where they bend) with the hands on the hips: He stood, arms akimbo, refusing to move.
"arms akimbo" として使う場合が多い様です。"akimbo" について、Word Detectiveでも取り上げています。http://www.word-detective.com/091400.html#akimbo
