Those methods were probably used often in PIE. Languages like English, which don't have a lot of combinations like that, come from earlier, more typical Indo-European languages. English comes from Anglo-Saxon, a Western Germanic language. The fact that English once was synthetic like German is shown by cranberry morphemes, which are so called because the "cran-" is a fossil of a word that no longer exists. Also, "mulberry" and "raspberry", where also the first syllable is a bound morpheme.
