Ancestry of English
Didn't English evolve from a Germanic language anyway? So this is just it coming full circle :-)
In general, no. English is actually a relatively recent new language (compared to Greek, German or French).
It was formed by the amalgamation of the Germanic language spoken by the English Saxons, with the Norman-French spoken by the 1066 invaders. As the communities merged, a creole (technical linguistic term) developed. To see what was happening, get a copy of Chaucer's "Canterbury Tales" that has the original on one side of the fold and a modern English translation on the other. Chaucer was near the start of the process. The Saxon proto-English used by the peasants, and the French proto-English used by the nobles, are still quite different, but coming together (his pilgrims understood each other without translators). It's a good read, by the way. Then watch a play by Shakespeare (who perfected the unified English Language, or maybe even invented it). You shouldn't need any translation.
The process slowed down after Shakespeare, but hasn't stopped. In particular, the grammars of Norman French and Saxon were incompatible, and English has been and is progressively jettisoning its grammar. It is quite possible English will evolve into a pure placement-positional language over the next few centuries (more like Chinese in structure, than anything else of Indo-European origins). The collision between two languages may also be the reason why English has voraciously assimilated words it needed to plug gaps real or imagined in its own vocabulary, from any source, or by neologistic invention. (Is neologistic a word? Do I care? )
Back to "shitstorm", it's no surprise at all that both parts of the word are of Germanic origin. English has preserved a distinction between "polite" words of French (noble) origins, and "rude" ones of Saxon (peasant) origins, which are synonyms or almost so. (e.g. "tempest" vs "storm", "execrement" vs "shit"). Many languages (including, I'm told, Gaelic and Arabic) don't have any rude words, and one has to employ florid combinations if one wishes to offend. "May the fleas of a thousand camels infest your armpits" and suchlike.
