I wonder if deciding where word boundaries should be was not always obvious. Italian "give it to me" can be three words or one depending on order. me lo da / dammelo. Lots of verb conjugations are basically contractions of the root/infinitive with a version of have/be. scriverai (scrivere hai) you will write (to write you have). Combine that with a fixed written language and constantly evolving spoken language, and it gets muddier. Like my first example, since classical Latin didn't have articles but late Latin did. Would like to hear from native speakers of Romance/neo-Latin languages if that seems plausible or like total bs.
