What you are describing is the root of a word. Prefixes and suffixes can modify that meaning (for example, by expanding, contracting, or reversing it) but the basic meaning does not change.
For example: the verb 'develop' means 'to bring to a more advanced state'. The adjective 'developed' means 'having been brought to a more advanced state'. 'Undeveloped' means 'not having been brought to a more advanced state'. 'Over-developed' means 'having been brought to an inappropriately advanced state'. 'Under-developed' means 'not having been brought to a sufficiently advanced state'.
