How to divide words with silent consonants?

I wonder how to divide words such as 'assumption' at the end of line, when a consonant (in this case 'p') in the middle of the word is silent (/əˈsʌmʃən/).

Which syllable (and line) does the "p" belong to?

assump- tion

or

assum- ption

My guess is that the first division looks better because 'tion' is a common suffix itself, but am not sure?


Solution 1:

When in doubt, find a dictionary that lists syllables.

Example:

as‧sump‧tion /əˈsʌmpʃən/
Longman

This pronunciation claims the p is not silent.
