When learning any language it is always good to know when to use certain vocabulary words. Some words might be used in formal situations while others may be used in everyday conversation.
To ask which word is used most commonly say:
"Which word is used most commonly?"
or
"Which word is used the most?"
In most English speaking countries, the word 'bike' is used more commonly when speaking about a bicycle. However, the word 'bike' also refers to a motorcycle, so be careful not to confuse the two.
例：Which word is used the most, bike or bicycle?
「bikeとbicycle、どちらが普通に使われますか？」
例：Which word is used most commonly?
「どちらがよく使われている表現ですか？」
例：Which word is used in everyday conversation?
「どちらの表現が毎日の会話で使われていますか？」
外国語の学習では語彙を増やすことが大切です。
単語によって、毎日普通に使われるものや、フォーマルな場面でしか使われないものがあります。
英語圏では、"bike"が一番よく使う表現です。
しかし、"bike"はエンジン付きのバイクにも使えるので、気をつけましょう。
Which word is more common in English, 'bike' or 'bicycle'?
Which word is more commonly used, 'bike' or bicycle'?
You can use either the adjective ('common') or an adverb ('commonly') to inquire about the usage of certain words. If you use the word 'common', you do not need a verb ('Which word is more common..?') However, if you use 'commonly' you need a verb 'use' ('Which word is more commonly used?').
Moreover, when it comes to the usage of words 'bike' and 'bicycle', they are synonyms, however, you can use the word 'bike' to refer to a motorcycle as well. Also, you can use 'bike' as a verb ('Would you like us to bike to the city center, or walk?'). This usage is informal, so it's best to avoid it in most standard written contexts.
例：Which word is more common in English, 'bike' or 'bicycle'?
「'bike'と'bicycle'、どちらが一般的な表現ですか？」
例：Which word is more commonly used, 'bike' or bicycle'?
「「'bike'と'bicycle'、どちらが一般的な表現ですか？」
形容詞'common'や副詞'commonly'が「一般的な」もの聞くのに適しています。
例文１の'commen'はbe動詞の後にきますが、例文２の'commonly'は'use'の動詞も使わねばなりません。
もっと言えば、'bike'と'bicycle'は同意語です。
しかし'bike'はエンジン付きのバイクも指します。
また動詞として使うこともでき、'Would you like us to bike to the city center, or walk?'「シティ・センターにいくのに、自転車でいく？それとも歩いて？」のように使えます。
これは砕けた表現なので、文章にはあまり書かないようにしましょう。
