My name is Matthew Radich. Often my students call me "Mr. Matthew". To an English speaker, this is strange*. Why? It's because using a person's first name is very casual, but using "Mr." is very formal. It's a strange mix of polite and casual. It is like being called 「なべ様」 if your name is 渡辺.

In informal English (spoken and written), it is sometimes possible to drop the subject from your sentence. Generally speaking, you can only do this if both of these two things are true:

1. the word you drop is a pronoun; and
2. it is the first word in the sentence.

Compare these two sentences:

1. I went for a drink with a friend from work; and
2. Went for a drink with a friend from work.

Infinitives are generally made like this:

to + VERB

Sometimes they are used with out "to". Infinitives are verbs, and so they come in many forms:

1. progressive forms;
2. perfect forms;
3. passive forms; and
4. negative forms.

The infinitive is a form of the verb, usually used with "to". Sometimes an infinitive does not use "to" (that's why "to" is in brackets below). Infinitives look like this:

• (to) go;
• (to) do;
• (to) watch;
• (to) see; etc.
