For example, these questions:
- Common 四字熟語 that use/are 当て字
- Which verbs have 辞書形 (dictionary forms) that look like ~ます conjugations?
And these to a lesser extent:
- 外来語 (gairaigo) replaced by Japanese word?
- Are there any old loanwords from Korean, especially any not written in katakana?
From the FAQ: "You should only ask practical, answerable questions based on actual problems that you face." Questions of the form "Here are some examples of words that have [this property], what are some others?" can be hard to answer definitively. To a lesser extent, "Are there any words that have [this property]?" can also be hard to answer if the poster is looking for all such words instead of just a few examples.
Some of the other SE sites prohibit these kinds of questions; what should we do?
