What do you put in as the subject marker if there is more than one subject?
For example

> Adam と Sarah ___ すしがすきです.

question
grammar particles particle-は particle-と particle-が
Should you use は or が when you have a compound subject?
The particle will be the same regardless of number, so you would use は.
Whether it's one person or two hundred people who like sushi, the particle
will not change.

> AdamとSarah **は** すしがすきです。

answer
Just the same as if there was only one person:

> AdamとSarahはすしが好{す}きです。

The topic of the conversation, marked by は, is the pair of both Adam and
Sarah. Topics can be very complex phrases; they don't have to be just single
words.
