Why does the word eshgh (love) have an -i attached to the end of it to make eshghi?
This -i is a special marker used before relative clauses. Because eshgh is explained by the phrase starting with ke (that), we add -i to signal that we are about to describe this specific love. Even though -i usually means "a" or "an", here it acts as a bridge roughly meaning "the love that...".
Why is jazāb-tarin (most attractive) placed before the noun, and does it use an ezafe?
Superlative adjectives ending in -tarin always come before the noun they describe, and they never take an ezafe connector. That is why it is jazāb-tarin eshghi without any extra linking sounds between the adjective and the noun.
How is the verb dide-am (I have seen) formed?
dide-am is in the present perfect tense. It is built by taking the past participle dide (seen) and adding -am, which is the present tense "to be" ending for "I".
How would this sentence sound in everyday spoken Farsi?
In casual conversation, ast (is) becomes -e, so eshghi ast blends into eshghi-e. Also, dide-am is usually shortened to didam. So you would likely hear: in jazāb-tarin eshghi-e ke man didam.
