Prefixed verbs can be derived from basic verbs or from another prefixed verb. With the prefix "her-" ("again, re-"), it is also possible to derive prefixed verbs from separable verbs, but such verbs are often defective, with the separated (V2-affected) forms often being avoided by speakers. For example, the verb "herinrichten" ("to rearrange, to redecorate") is a combination of the prefix "her-" and the separable verb "inrichten". According to the syntactical rules, this must become "Ik richt de kamer herin." ("I redecorate the room"), but using "herin" as a separable particle is often avoided as it is not an independent word (unlike the separable particles of most other verbs). Many speakers choose to rephrase it using the adverb "opnieuw" ("again, anew"): "Ik richt de kamer opnieuw in." In subordinate clauses or with a non-finite verb, there is less objection: "Mijn vriend keek toe, terwijl ik de kamer herinrichtte." ("My friend looked on, while I redecorated the room.") or "Ik heb de kamer heringericht." ("I have redecorated the room.").
