A friend (not a linguist) told me (not a linguist) that the Basque language -- Euskara -- has certain elements that are not well understood in historical context, in terms of uniqueness compared to surrounding languages. Here are some things I found while casually researching the topic:
Euskara is known to be a 'free word order' language; this means that the order of the phrases in the sentence can vary article
Spanish permits "every possible word order"?Basque and Spanish are diametrically opposite in many respects. The position of the head is one amongst many differences; Basque is head-final whereas Spanish is head-initial. Therefore, the basic word order in Basque is SOV and SVO in Spanish. Nevertheless, they both share some properties, both having strong verb morphology able to licence pros and displaying free word order. In both languages, every possible word order combination can occur. article
Turkish is also a free word-order language. article
Then the opposite, when what we know as multiple words are bound into one word:Estonian has a comparatively free word order article
And from same source:there is no independent Navaho word to mean mother or father, sister or brother, ear, tooth, or leg, or even shoes or bow and arrow ... one must use morphologically complex words meaning someone's mother, someone's father article
In analytic languages words tend to consist of free morphemes, i.e., they are monomorphic. Chinese and Viet. are the most purely analytical: nearly half their words are monomorphic, and also monosyllabic. Since analytic languages usually have relatively few derivational or inflectional morphemes, they tend to form words by combining free morphemes into compounds. Thus a preponderance of both simple and compound words tend to be a feature of analytic languages. Nearly half of all Chinese words are monomorphemic, and most of the rest are compounds of the type gascan, blackboard, etc, such as dianhua telephone, or diankan TV. Of all the European languages, English is the most analytic, and it also contains many compounds.
