"J'aimerais avoir"
Here's how it breaks down:
* J' - This is the contraction of "je" (I) and "ai" (have).
* aimerais - This is the conditional form of the verb "aimer" (to love, to like)
* avoir - This means "to have"
You can then add what you would like to have after this phrase. For example:
* J'aimerais avoir un café. (I would like to have a coffee.)
* J'aimerais avoir une pizza. (I would like to have a pizza.)
* J'aimerais avoir plus d'informations. (I would like to have more information.)
Other options:
* Je voudrais avoir (more formal than "j'aimerais avoir")
* Je souhaiterais avoir (even more formal than "je voudrais avoir")
The best option depends on the context and the level of formality you want to convey.
