* Hzl: This is a common abbreviation used in some contexts, particularly in informal writing or online.
* Haz: This is a shorter, more informal abbreviation that is occasionally used.
* H: This is a very short and simple abbreviation, but it can be ambiguous as it could stand for other things.
Ultimately, the best abbreviation to use will depend on the specific context and audience. If you are unsure, it is always best to spell out the word "hazel" in full.
