Actually no. It is a seperable verb, but its correct spelling is achteromkijken (and it has one emphasis: on "-om-"). It does need to be moved. Jcwf 03:40, 9 October 2009 (UTC)
Okay move. Any objections to that? Mglovesfun (talk) 07:42, 9 October 2009 (UTC)
Interestingly it occurs both as two separate words and as one. Compare:
Heb je al áchterom gekéken? - Did you have a look behind the house yet?
Heb je al achterómgekeken? - Have you looked over you shoulder yet?
Unfortunately for non-native speakers the stress marks -although a legitimate component of the spelling system- are seldom used because for native speakers the context (and the concatenation of the spelling) usually are enough to prevent confusion. Jcwf 12:01, 9 October 2009 (UTC)
Renamed by Jcwf, looks okay to me. Mglovesfun (talk) 17:48, 12 October 2009 (UTC)
