the "gh" is pronounced like "f" la-f-ter
Perhaps it has been spelt, rightly or wrongly, according to the pattern of light, night, right etc, which probably did have an extra sound (phoneme) in them. This phoneme has now disappeared from the pronunciation of these words but it originally represented a consonant similar to ch [as in loch]. Delight probably has a quite different etymology to the other gh words.
No. Middle English is two words.

Although "gh" has the sound of "f" in some words with "ough" (and "laugh"), the words though, high, and night have a silent gh, the words ghost and aghast have a silent h, and the word bigheartedseparates the pair into two syllables.
