English has two ways of talking about now, and they mean different things.
Present simple
For things that are generally true, habits, and routines.
```
I work in a hospital.
She takes the bus every morning.
Water boils at 100 degrees.
```
The form. Add -s for he, she and it. Nothing for I, you, we and they.
| Positive | Negative | Question | |
|---|---|---|---|
| I / you / we / they | I work | I do not work | Do you work? |
| he / she / it | She works | She does not work | Does she work? |
Notice that the -s moves to does in negatives and questions. It is never in both places.
```
✗ Does she works here?
✓ Does she work here?
```
Present continuous
For things happening at this moment, and for temporary situations.
```
I am working right now, call me later.
She is taking the bus this week because her car is broken.
```
The form. am / is / are plus the -ing form.
The difference in one pair
```
I live in Manchester. (permanently, this is my home)
I am living in Manchester. (for now, it is temporary)
```
Both are correct English. They say different things.
The verbs that resist -ing
Some verbs describe states rather than actions, and they usually stay in the simple form:
like, love, hate, want, need, know, understand, believe, remember, belong, seem, own
```
✗ I am knowing the answer.
✓ I know the answer.
✗ She is wanting a coffee.
✓ She wants a coffee.
```
Think and have belong to both groups, with different meanings:
```
I think it is correct. (opinion, a state)
I am thinking about it. (mental activity, happening now)
I have a car. (possession, a state)
I am having lunch. (an activity)
```
Spelling the -ing form
- Most verbs: just add -ing. work → working
- Ending in a silent -e: drop it. make → making, write → writing
- One vowel between two consonants, stressed: double the last one. run → running, sit → sitting, begin → beginning
- Ending in -ie: becomes -ying. lie → lying, die → dying
