Final answer:
The suffix that means 'to bear, bring forth' is '-fer'. Changes often occur when combining stem nouns and suffixes, as seen with 'neighborliness'. The suffix '-ed' varies in pronunciation and adds the past tense or completed action to verbs.
Step-by-step explanation:
The suffix that means 'to bear, bring forth' is '-fer'. A common example of this is in the word 'transfer', which is made up of the stem 'trans-' (across) and '-fer' (to bear or carry).
When analyzing stem nouns and suffixes, changes may occur. For instance, in 'neighbor + 1 + i + ness', the bringing together of the stem and suffixes changes '1' to 'li' to form 'neighborliness' due to the rules of English spelling.
Similarly, when combining stems and suffixes that bring about the sound [ē] spelled as 'i + es', such as 'hurry + i + es', it would result in the plural form 'hurries', where the 'i + es' brings about the necessary spelling and sound changes.
In the case where the suffix '-ed' is used, it can have different pronunciations depending on the verb it is attached to, adding meanings such as 'in the past' or 'action completed'.
