Which spelling variant
At Q-Park, when writing in English, we use UK spelling with S (-ise) not Z (American). If in doubt, consult the online Collins English dictionary (free access).
For your reference, here are some preferred spelling examples of commonly used words to write with S and not Z:
Do | Don’t |
digitalisation | digitalization |
organisation | organization |
maximise | maximise |
monetised | monetized |
optimised | optimized |
optimising | optimizing |
realised | realized |
recognised | recognized |
utilisation | utilization |
Here are some other common UK-US spelling variants to note:
Do (UK spelling) | Don’t (US spelling) |
colour neighbourhood travelled | color neighborhood traveled |
One or two Ss, Ts?
Words where the letter may be doubled before the ending – both forms are correct, but at Q-Park we use the variant with a single letter:
Do | Don’t |
focused/focusing | focussed, focussing |
benefited/benefiting | benefitted/benefitting |
bus, buses | busses |
