Thread: колебается

In an exercise I see the following phrase:
"Курс доллара в обменных пунктах, правда, чуть снизился, и колебается в центре города от 3700 до 4000 рублей за доллар".
But колеб/áться н.в. I see in Морфологический анализ conjugated as: колéбл/юсь, -ешься and not колебá/юсь etc.
However, I find in the net used widely this second form. I don't see any c.в. that could produce a different pattern for this verb.
I suppose that both forms are accepted. Isn't it? Thank you.

The only correct version is "колеблется". The usage of the other form shows the lack of grammar knowledge.

Thank you.

I don't know what Russian Grammar as a science has to say about it, but I would much prefer "колеблется" in that sentence, and I prefer this form generally as well.

(Пока я отвлекалась, всё уже разрешилось).
Я думаю, что колеблется было бы правильно. Колебается, мне кажется, слишком разговорно. "Колебается в центре города" вообще что-то смешное.
В прошедшем же времени будет только колебалось, колебалась, колебался, колебались.

Thanks again.

This usage shows a tendency in Russian language to replace nonproductive paradigmas of verbal conjugation by a productive one (like делать). В 19 веке люди говорили "ичет", "глочет" вместо "икает", "глотает".

OK. This shows a "generous" tendency. Usually more used are some verbs, more irregular they are, to make them easier to pronounce. Here the people tries to make a less regular verb (in the mesure one case say that of Russian verbs) more "regular". In any case, "it's a long way to Tipperary ". Thank you.

It's an irregular verb. According to the general pattern its 3rd person should be "колебётся", but for some reason it is "колеблется".

Как в стебётся, дерётся, крадётся, рвётся?

...берётся и так далее.

As far as I understand here the only "irregularity" present is the accent of 1st. p. sing. not being at the end.
Let's me explain.
колебáться I if its stem is
1) колеба- (as резать) then would be колеблý, -ёшь, -ёт ; or moving the accent from the 2nd person: колéблешь, ...
2) колебай- (as делать) then would be колебай-у, колебá/ю, -ешь, -ет
So being, as it is, the stem колеба- the only "irregularity" that I see is колéблy instead of колеблý.

Ready to accept stones on my head

Тогда было бы "колебУ", "колебёшь" и т. д.

л is inserted in 1 p. sing. in the second conjugation, and in a few verbs of the fist conjugation in all the forms if the ending is unstressed (cыпать-сыплет). However many prople say сыпит now.
There is another tendency, found in the vernacular Russian. Verbs loose changings of г, к into ж, ч in the Present tense. For example, some people say стигёт (от стричь) instead of стижёт, пекёт (от печь) instead of печёт.

Very interesting. Thank you.

A typo, I suppose...
