Why is it ''the MRT will close'' and not ''an MRT will close''?
If we use 'an' with vowel sounds and 'the' with consonant sounds and M sounds like em why is it 'the'?
If the subject MRT is already understood between the speakers does it override the the an rule?
Why do we sometimes completely omit the or an?
''I play piano.''
''I ride horses for a living.''
