Question

Identify the word with a different sound represented by the two underlined alphabets at the final level in one of the following words:
1. catch
2. watch
3. match
4. patriarch

Answer 1

Correct Answer - Option 4 : patriarch

Here the correct answer is Option 4 i.e. patriarch.

:- 
When we speak words like catch,watch and match, the suffix sounds like 'ch'.
But when we speak the word 'patriarch' it sounds 'arch' not 'ch'.
'ch' is a suffix in all the words but  'arch' is the pronunciation of the suffix of the word patriarch, and  not 'ch'.
Hence, it is different from the other words.

A prefix is a group of letters (or an affix) that's added to the beginning of a word, and a suffix is an affix that's added to the end of a word. 
Prefixes modify the meaning of a word.
A prefix is a group of letters placed before the root of a word.
For example, the word unhappy consists of the prefix un- [which means “not”] combined with the root (or stem) word happy; the word unhappy means not happy.
 A suffix is a group of letters placed after the root of a word.
