    This word is like a Swiss Army knife. It has many uses. The meaning changes with how you use it. Look at the words around it to understand.

    This is different from other words like it. 〜だらけ is for bad things covering something. 〜まみれ is for messy stuff like mud. 〜ずくめ means completely one thing, often for ideas. 〜いっぱい is the most general and not usually negative.

    Watch out: Do not mix up "いっぱい" and "だらけ." "いっぱい" means full of something. It can be good or bad. "だらけ" means full of bad things. For example, a room full of trash. If a stadium is full of people, use "人でいっぱい." Do not use "人でだらけ." That would mean the people are a problem.

    たくさん

    This word means 'a lot' or 'many'. You use it when there is a big amount of something.
