Meboshi wo Tsukeru (目星をつける)

It is important to make an educated guess or establish a goal when you conduct/investigate something.

Such making an educated guess is often called "meboshi wo tsukeru (目星をつける)" in Japan.

"Me (目)" means "eye," "boshi (星)" usually means "star," but it also means "mark" derived from "star mark."

Since "tsukeru (つける)" means "to put/attach something," the literal meaning of "meboshi wo tsukeru" is "to put a mark."

In turn, this term has come to mean "to make an educated guess" or "to establish a goal."

目星をつける

何かを遂行・調査するとき、見当をつけたり目標とするところを定めることは重要です。

このように見当をつけることを、日本語では「目星をつける」と言います。

「目」は 'eye' を、「星」は的の中央につける星印から転じて 'mark (印)' を意味します。

「つける」は "to put/attach something" を意味するため、「目星をつける」の文字どおりの意味は "to put a mark (目印をつける)" となります。

これが転じて、「見当をつける」や「目標を定める」という意味で使われるようになりました。
