Questions about isolating language

[Macnerd]

Since isolating languages use no inflection & no helper words like modal verbs, how would an isolating language express a modal verb such as "I may dwell"?

In the Arby's phrase "grass-fed beef", "grass" is a noun, "fed" is the past participle of the verb "feed". Participles can act as adjectives. Nouns can act as adjectives as in "apartment building". They are called attributive nouns. So, the phrase "grass-fed" is acting like an adjective & modifying the noun "beef". Since an isolating language uses no inflections & helper words, how would it express the Arby's phrase?
