The emphasis in the word "beet" is on the first syllable
According to the norms of the modern Russian language the emphasis in the word "beet" falls on the first syllable – the "e". The pronunciation of the word "beets" through "e" with the accent on the last syllable is considered an error, and rude. In the dictionary even emphasized the inadmissibility of the fallacy of pronouncing "beet" with the accent on the "a".
This emphasis is maintained in all cases, singular and plural: beets, beets, beets, beets and so on.
However, words formed from the word "beets," the emphasis may shift. So, the diminutive "nice beet, huh" is pronounced with the accent on the second syllable, the emphasis here is on "o". The same thing happens with the word "beet," the emphasis here also falls on "about".
Why in the word "beet" is the correct accent on the "e"
The word "beets" is composed of the letter "e", which is in the Russian language "special". And one of the features is that the sounds are transmitted with this letter are always under stress. The only exceptions are some borrowed or difficult words. But "beet" the exception does not apply.
At the same time the letter "E" often replaced by "E" according to the rules of the Russian language "letter points" required for writing the only books for children that are just starting to learn to read, and in cases where it is necessary for the transfer of pronunciation (e.g., in place names or surnames) or similarsocial plays a role (for example, the words "all" and "all" mean different things). The word "beets" to the number of words where the use of "E" definitely does not apply. Therefore, most of his writing through "e", and together with points on e disappears, and the indication of the pronunciation of the word.
This is probably one of the reasons why many are beginning to say "beet" through "E" with the accent on the last syllable. Recall, it is considered rude speech error.
