This site will be taken down March 31st, 2026.

This was not an easy decision to make. For the last couple years, I have been struggling to find motivation for this site and to keep up with basic maintenance and security updates. With the rise of AI and more sophisticated tools, the usefulness of sites like this is questionable and traffic has nose-dived. I just don't have it in me to keep doing this. Thank you all for 10 years of support!

Sentence

canは助動詞ですので、疑問文では文頭に持ってきます。

canは助動詞(じょどうし)ですので、疑問(ぎもん)(ぶん)では文頭(ぶんとう)()ってきます。
'can' is an auxiliary verb, so in question sentences it is brought to the start of the phrase.
Sentence

この文は現在完了形です。haveは動詞ではなく、助動詞。

この(ぶん)現在(げんざい)完了形(かんりょうがた)です。haveは動詞(どうし)ではなく、助動詞(じょどうし)
This sentence is in the present perfect. 'have' is not a verb, but an auxiliary verb.
