覚え方のコツ Memory Tip
guessing は guess「推測する」に -ing を付ける際、語末の s を重ねずそのまま guessing とする。発音は /ˈɡesɪŋ/。「be guessing the answer」「keep guessing」の形で、十分な情報がないまま答えを考える動作を表す。estimating は数量を概算する語なので、答えや人物を当てる guessing と区別する。
Guessing is made by adding -ing directly to guess; do not double the final s. It is pronounced /ˈɡesɪŋ/. Use be guessing for an action in progress, as in “She is guessing who sent the letter,” and keep guessing for repeated attempts. The key idea is answering without enough certain information. Compare estimating, which commonly involves calculating an approximate amount, cost, size, or time. Guessing is broader and often suggests that the speaker has less evidence to rely on.

彼女は誰がその手紙を送ったのか推測している。

先生が説明するまで、彼らは結果を推測し続けた。

guessing の語源・成り立ち Etymology
guessing は guess に動作を表す -ing が付いた形です。guess は中英語 gessen にさかのぼり、オランダ語 gissen や古ノルド語系と近縁で、もとは「手探りで当てにいく」感じでした。関連語は guesswork、get。
Guessing consists of guess plus the participial or gerund ending -ing. Guess entered English in the Middle English period as gessen. Its deeper origin is uncertain, though it is commonly compared with words such as Dutch gissen, “to guess.” The modern verb refers to reaching an answer without certain knowledge, while -ing presents that act as ongoing or treats it as an activity.
