Nasal Assimilation

Listen to the following phrases beginning with ‘In’.  How is the /n/ pronounced in each case?

In Brighton
In Canada
In September

/n/ changes to /m/ in ‘In Brighton’,
/n/ changes to /ŋ/ ‘In Canada’,
/n/ doesn’t change in ‘In September’

When do nasal assimilations occur?

  • In connected speech, the sound /n/ often assimilates to /m/ or /ŋ/.
  • If /n/ is followed by a bilabial consonant (p,b,m), it can assimilate to /m/.
  • If /n/ is followed by a velar sound (k,g), it can assimilate to /ŋ/.
  • If /n/ is followed by a vowel or any other consonant, it will normally remain as /n/.

DRILL

/n/ = /m/: drainpipe, rainbow, entertainment, in Bath, in Poland, on Monday.

/n/ = /ŋ/: incase, think, painkillers, increase, in Canada, in Cambridge, in Ghana.
