"Regular" would be the classic linguistics term, would it not? Although computer science limits the term to the use of regular languages in the Chomsky hierarchy sense (that is, more specifically to regular expressions and the languages they describe), I am under the impression linguistics as a whole treats regularity as a multivariate spectrum. Some languages have more regularity in terms of grammar productions or morphology than English.
That points to Isolating [1] and I think highly isolating may be the more useful distinction to this specific example. (Modern English is rather analytic, having dropped most, but not all, inflections in the Middle English era. Mandarin Chinese is much more isolating than Modern English.)
