title_body: What are some strategies for setting verbs apart from other words without knowing it's a verb
upvoted_answer: In Lojban, cmevla (proper nouns, like .alis.) are the only words ending in a consonant. Depending on how big your vowel inventory is, you could make all verbs end in a vowel and everything else end in a consonant. That way, they are easy to pick out and still provide much variety.  
  
  To generalize that, you could just take the last sound of a verb from any distinct group of sounds, like nasals, fricatives or labiliased consonants ("labialiseds"?). One could also use that to make word correspondences, e.g. nominalization changing the verb's final sound to the corresponding nasal.  
  
  You also mentioned position in the sentence. Having the verb in a specific position (first, last, second, etc.) is a good way to distinguish them, but depending on your language, dependent clauses could get difficult.
  Of course, coupling position in sentence with a specific ending sound provides a nice way to recognize sentence borders. There, one could again use the ending sound kind to modify the verb to signify a dependent clause.
