Japanese Grammar – Only I know the password. 🇯🇵

わたし____は この パスワード を しっています。

Explanations of why this is the answer:

1. Grammar Function:
– だけ (dake) is used to indicate "only" or "just" in Japanese, specifying that something is exclusive or limited to a certain condition or scope.

2. Position in Sentence:
– In the sentence "わたし____は この パスワード を しっています。" (Watashi ____ wa kono pasuwādo o teimasu), the blank must be filled with a word that specifies "only I."
– だけ (dake) directly follows the noun or pronoun it restricts, in this case, "わたし" (watashi), making it "わたしだけ" (watashi dake) to mean "only I."

3. Comparison with Other Particles:
– ただ (tada): While ただ also means "only" or "just," it is not used in the same grammatical structure as だけ and is typically used at the beginning of a sentence or clause.
– しか (shika): Requires a negative verb form to restrict the sentence in a negative way, e.g., "わたししか知らない" (watashi shika shiranai – Only I do not know). This wouldn’t fit with "しっています" (teimasu), which is affirmative.

Example Sentences for Context:
– 彼だけが知っている (Kare dake ga teiru) – Only he knows.
– 今日は仕事だけ (Kyō wa shigoto dake) – Today, there is only work.
