It's simply a linguistic/phonetic break down of the sounds when you're going through a syllable change and you have that hard 'ch" sound. Part of the ch is in the first syllable. Which part? I guess the 't' makes lakes logical sense phonetically. You can do a hard stop without the t, but it's hardly a difference, IMO.

Ahhh yes, makes perfect sense. Thanks!
