A. How to Pronounce -ed in English
The past simple tense and past participle of all regular verbs end in -ed. For example:
| base verb (v1) | past simple (v2) | past participle (v3) |
|---|---|---|
| work | worked | worked |
In addition, many adjectives are made from the past participle and so end in -ed. For example:
- I like painted furniture.
The question is: How do we pronounce the -ed?
| If the base verb ends in one of these sounds: | example base verb*: | example with -ed: | pronounce the -ed: | extra syllable? | |
| unvoiced | /t/ | want | wanted | / Id/ | yes |
| voiced | /d/ | end | ended | ||
| unvoiced | /p/ | hope | hoped | / t/ | no |
| /f/ | laugh | laughed | |||
| /s/ | fax | faxed | |||
| /S/ | wash | washed | |||
| /tS/ | watch | watched | |||
| /k/ | like | liked | |||
| voiced | all other sounds, for example... | play | played | / d/ | |
| allow | allowed | ||||
| beg | begged | ||||
* note that it is the sound that is important, not the letter or spelling. For example, "fax" ends in the letter "x" but the sound /s/; "like" ends in the letter "e" but the sound /k/.
- he aged quickly /d/
- he blessed me /t/
- they dogged him /d/
- he has learned well /d/ or /t/
The pronunciation depends on the sound at the end of the infinitve of the main verb and whether it is voiced or not.
| /Id /infinitives that end in the sounds /t/ or /d/ | / d / infinitives that end in a voiced sound | / t / infinitves that end in an unvoiced sound |
| needed hated dated seated | lived chilled enjoyed tried | shopped picked wished crunched |

B. Do vs. Make
Do and Make are two verbs which frequently confuse students. Here we will learn about the difference between Do and Make and when to use each one.
When do you use DO?
DO is used as follows:
1. DO is used when talking about work, jobs or tasks. Note, they do not produce any physical object.
- Have you done your homework?
- I have guests visiting tonight so I should start doing the housework now.
- I wouldn't like to do that job.
2. DO is used when we refer to activities in general without being specific. In these cases, we normally use words like thing, something, nothing, anything, everything etc.
- Hurry up! I've got things to do!
- Don't just stand there – do something!
- Is there anything I can do to help you?
3. We sometimes use DO to replace a verb when the meaning is clear or obvious. This is more common in informal spoken English:
- Do I need to do my hair? (do = brush or comb)
- Have you done the dishes yet? (done = washed)
- I'll do the kitchen if you do the lawns (do = clean, do = mow)
When do you use MAKE?
Make is for producing, constructing, creating or building something new.
It is also used to indicate the origin of a product or the materials that are used to make something.
- His wedding ring is made of gold.
- The house was made of adobe.
- Wine is made from grapes.
- The watches were made in Switzerland
We also use Make for producing an action or reaction:
- Onions make your eyes water.
- You make me happy.
- It’s not my fault. My brother made me do it!
You make after certain nouns about plans and decisions:
- make the arrangements,
- make a choice
We use Make with nouns about speaking and certain sounds:
- make a comment
- make a noise
- make a speech
We use Make with Food, Drink and Meals:
- make a cake
- make a cup of tea
- make dinner
Compare Do and Make
A: You have to make a cake for Simon.
B: I’ll do it later.
Notice how in the response the verb DO is used. This is because the meaning is clear and to avoid saying “I’ll make it later.” which could sound repetitive.
