Mártan Ó G

In compound words the second word generally takes a ‘h’ like in léamhthuiscint (léamh + tuiscint).

This ‘h’ is blocked in cluastuiscint because of the Dentals Rule which means you can’t put a h on a d, t or s if it’s proceeded by a d, t, l, s or n.

Google Dentals Rule Irish for more info.
