Text for Dimensions – Read this before you try the questions.

The objective of this lesson is that you can speak about dimensions and measurements easily using adjectives and the corresponding verbs and nouns.

Look at the drawing of a proposed swimming pool with a diving board.

We can express the dimensions using the verb ‘to be’ + an adjective:- “The pool is 15m long” or we can use ‘have’ and a noun: “The pool has a length of 15m”.

Originally the pool was going to be 12m long but the architect decided to lengthen it by 3m, from 12m to 15m. In this case we are using a verb ‘lengthen’ meaning to make something longer.

Also notice the prepositions: ‘by 3m’ indicates the difference in length between the first proposal and the current one, ‘from’ tells us the original length and ‘to‘ indicates the final length.

This pool will be rectangular so it has four sides: a left side and a right side, 12m long and two ends, the deep end and the shallow end which are 6m wide. The deep end is 2.5m deep but the shallow end is only 1.2m deep. (Notice we DO NOT say 1.2m shallow).

We can also see that the retaining wall is going to be 0.25m thick.

The architect is also planning a diving board that is 1.8m high but the client thinks that this is dangerous as the pool is less than 2.5m deep at the point where a diver will enter the water.

In general, we use the adjective ‘deep’ to describe measurements that go down, in this case below the level of the ground, but we use ‘high’ to describe measurements that go up, the diving board is above ground-level.

Task: Read the 3 questions below and try to think about the answers, you do not have to write anything. In the next section you will complete an online task to test you.

  1. So far we have used the words ‘long‘ (adj), ‘length‘ (noun), ‘lengthen‘ (verb) but for the other dimensions we have only used the adjectives ‘high’, ‘wide’, ‘deep’, ‘thick’ and ‘shallow’. Do you know the corresponding nouns and verbs for these adjectives? One of the words does not really have a corresponding verb and another the verb is only used in another context, not physical dimensions.
  2. Here the adjective thick is describing a solid object, a wall. It can also describe a liquid. Do you know the meaning of a ‘thick liquid’? What word would you use in your language?
  3. What is the opposite of the word ‘thick’?
