It takes two to tango.

Tim: You might remember from a previous video that when the sound /t/ comes in between two consonants, we don’t usually pronounce it.
But what happens if there is a vowel sound before the /t/? and the next word also begins with /t/?
Well, in this case the two /t/ sounds join together to create one slightly stronger /t/. So ‘it takes two’ becomes 'it takes two'. This is an example of twinning or gemination. Here are some more examples.
