Same sound, different spelling

To, too and two are homophones - they have the same pronunciation but different spelling: The music wasn't too loud and I talked to a lot of people, including two Italian girls.

Aloud and allowed are homophones: We're not allowed to read aloud in the library.

Other homophones are: hole / whole, know / no, meat / meet, passed / past, right / write, their / there, wait / weight, weather / whether

We use maybe (one word) to mean perhaps. This is different from may be (modal verb + infinitive without to). Similarly, already and all ready have different meanings. Compare:

I want my room yellow, or maybe orange.
I am not sure, but the teacher may be late today.
When I got to the cinema, the film had already started.
The students are all ready to go. (all the students are ready to go)

Note that we can say the other but not an other. We write another as one word:
I will write you another letter soon.
