No, but you can make a sentence with the word suddenly. Suddenly it started to rain.
Suddenly it occurred to me to try something different!!
Using commas with introductory adverbs is a stylistic consideration. Using a comma in this situation is never incorrect, but many writers have recently started omitting the comma. You could also try moving the adverb around in the sentence, expunging this problem completely: instead of saying "Suddenly, the filled cup fell off the table," you could write "The filled cup suddenly fell off the table," or "The filled cup fell off the table suddenly."
The linking verb in the sentence is "turned," as it connects the subject "it" to the adjective "dark."
No, the word 'suddenly' is not a verb; suddenly is an adverb, a word that modifies a verb (suddenly thought, suddenly appeared).A linking verb acts somewhat like an equals sign, the object is a form of the subject (Mary is my sister. Mary=sister); or the subject becomes the object (Mary felt cold. Mary->cold). The adverb 'suddenly' can modify the linking verb: Mary suddenly felt cold.
