Question: Question: These two seem very similar. What are the major differences between the two? For example, in the following sentence, Substitute the lesser punishment for the greater one. Can one use "less" instead of "lesser" here? 
Answer: Less refers to quantity, lesser refers to quality. Your sentence could be rephrased as "substitute less punishment for more punishment." Here we are saying that the amount of punishment is smaller. But if you say "substitute the lesser punishment" you are saying the type of punishment is not as severe. Forty lashes is less punishment than 100 lashes. Being pelted with rotten tomatoes is a lesser punishment than being pelted with rocks.

Answer: yes


Question: Question: "Vomit" is not a recent addition to English, and nor does it have a peculiar pronunciation. Yet, the past tense of vomit does not follow the notion that a vowel followed by a consonant and emphasis on the consonant. (For example, past tense of 'emit' is 'emitted'.) 
Answer: The crucial thing is that the last but one syllable of "vomited" has no stress. Not even secondary stress. So the final consonant doesn't double. By contrast, the last but one syllable of "emitted" has stress (because the last syllable of "emit" has stress). This issue is raised in this question, to which a good answer is given. Compare: (No stress) marketed, budgeted, edited (Secondary stress) combatted, formatted (Primary stress) patted, petted, pitted, potted, rutted.
