When one considers Indo-European languages, especially those which are properly European, one can perceive that there are many similarities among them. These similarities surely are due to their roots in the very distant past of civilized mankind, going back to the early Sanskrit language.
With the exception of a few cases, modern words for things, feelings, beings and thoughts that are very primitive, basic, ancient, well known and easily perceived by mankind are very simple and quite short.
Those words are nowadays short and simple and they were probably also that short since their ancient origin.
Even considering that most of the words in European languages with either simple or sophisticated meanings, are monosyllabic or bisyllabic, there is some pattern that confirms that nouns for well known things are generally shorter.
That perception is easy, even without any further deeper research.
Also, frequently-used verbs with simple, ancient meanings, which express feelings, behaviors and actions are usually short.
Almost all of these verbs are also very irregular, for example auxiliary and modal verbs;
Irregularity is quite obvious, because those verbs can be considered as "natural" ones. Rules to standardize languages came only later, when talking was systematized by people.
Why are such word short? This seems quite obvious: first things comes first. Primary languages first used most of possibilities of monosyllabic or bisyllabic sounds. When most sophisticated and complicated subjects required new words, there were few possibilities left for monosyllabic or bisyllabic words. So longer words were necessary.
Another easily realized language pattern, that has also obvious roots, is that there are more differences among words with the same meaning in different languages for ancient and traditional stuff, than for very recent, modern, technological, medical, nouns.
