Assimilation

The /ð/ sound in words like the, that, this can turn into /n/ in connected speech due to assimilation. This typically happens when /ð/ follows a word ending in /n/ or /m/, causing the /ð/ to be replaced by /n/ for smoother pronunciation.


Common Situations Where /ð/ → /n/

1. When "the" follows a word ending in /n/ or /m/

2. When "than" follows a word ending in /n/


3. When "then" follows a word ending in /n/


Why Does This Happen?

This change occurs due to assimilation, where one sound changes to become more like a neighbouring sound for smoother speech. Since /n/ and /ð/ are pronounced with the tongue touching nearly the same place, it’s easier to replace /ð/ with /n/ when preceded by /n/ or /m/.
