The word ends in / with (preposition choice)

Hello.

The word ‘lake’ ends in / with ‘e’, not in /with ‘k’.

Which preposition will be correct in this situation?

Hi,

This would be: The word ‘lake’ ends in (an) ‘e’ and not with a ‘k’. The word ‘lake’ ends with the letter ‘e’ and not with the letter ‘k’.

Thank you, Alan. One more question. Suppose it’s not about a letter but a combination of letters.

German words what end in [color=blue]a ‘ung’ are usually feminine. For example, “Haltung”

Must I still use the indefinite article?

I would say:

German words which end in ‘ung’ or with the letters ‘ung’ or with the suffix ‘ung’.

Thanks, again!
