I thank all of you who responded.

My question was not whether Russian words are long, nor did I intend to belittle the Russian language or its speakers. I wanted to know whether Russians are sometimes impeded by frequent, everyday words that have many syllables.

Some very common words can be shortened Здравствуйте-здрасте, человек-чек, сейчас- щас (the last one - nearly always). The rest are pronounced normally
Stop! = Остановитесь! You can say Стойте!
...in critical situations Russian commanders resort to offensive language (Russian mat) which shortens an average word length to... 3.2 letters. The reason is that some word combinations and even sentences can be replaced with one word...
Doesn’t the use of abbreviations or shorter substitutions in fact indicate that the original versions of words are found to be unwieldy?

May I answer you in Russian?
Yes. I wish that posters here would respond in both Russian and English (or their own languages). Then readers might be able to get a better idea of what the posters are endeavoring to express.

Да! Я желаю, чтобы писатели здесь отвечали и по-русски и по-английски (или на своих языках). Таким образом читатели возможно могут приобретать лучшую идею того, что писатели стараются выражать.
