In English, when a word ends in the letter ‘r’, and the next sound starts with a vowel, you pronounce the ‘r’ sound to connect the two words.

For example ‘far enough’. 

If a word ends in an ‘r’, and the next words start with a constant, for example ‘far down’, you don’t pronounce the ‘r’ sound.

Practice putting these examples of the linking ‘r’ into your English speech and you will sound like a native in English. 

When you’re listening to English, practice trying to hear the linking ‘r’ in others’ speech too.
