Learn Farsi: آن ورزشکار بااراده خیلی باملاحظه است. - That strong-willed athlete is very considerate.

Erâdeh is a noun meaning "will," "determination," or "willpower." By adding the prefix bâ- (which means "with"), we form the adjective bâ-erâdeh, which literally means "with willpower." In English, this translates naturally as "strong-willed" or "determined."

What is the base word inside bâ-molâhezeh (considerate)?

The base noun is molâhezeh, which means "consideration," "observation," or "tact." Adding the bâ- prefix turns it into an adjective meaning "with consideration," which we translate as "considerate."

How would I form the exact opposite of these two adjectives using this lesson's grammar?

You simply replace the bâ- (with) prefix with the bi- (without) prefix. Bi-erâdeh means "weak-willed" or "lacking determination," and bi-molâhezeh means "inconsiderate" or "thoughtless."

Is there an ezafe (linking vowel) between varzeshkâr and bâ-erâdeh?

Yes, you must pronounce an ezafe connecting the noun to its adjective: varzeshkâr-e bâ-erâdeh. Because the word varzeshkâr ends in a consonant, this short "e" sound is not written out in the Persian script, but it is grammatically required and you will hear it when native speakers read the sentence.
