I know that prefixes never change the spelling of the stem. However, their spelling changes in some cases. For example:
- well+come = welcome (not wellcome)
- all+ways = always (not allways)
- in+regular = irregular (not inregular)
According to some websites I've reviewed, suffixes sometimes change the spelling of the stem. Does it mean their own spelling never changes or sometimes it is possible?
Is it a valid deduction to say: Suffixes sometimes change the spelling of the stem, but their own spelling never changes. However, prefixes never change the spelling of the stem, but their own spelling sometimes changes.
