The word "好几" is formed through a straightforward semantic fusion where the character "好" (hǎo), which in this context functions as an intensifier meaning "quite" or "very", is placed directly before the character "几" (jǐ), which means "several" or "a few". The combination does not create a new fixed compound with an unpredictable meaning; instead, it simply and logically amplifies the quantity indicated by "几", resulting in a combined sense of "quite a few" or "a good number of". It is a direct, additive pairing where the first element modifies and strengthens the numerical vagueness of the second.
