Hi Marko, There are two adverbs of manner in your sentence; grammatically, this is certainly possible. In my opinion, the intonation may become awkward as both words end with -ly. We may not speak the same way as we write, vice versa. So, for example, we may need to modify our sentence structures to avoid sounding "clunky" if we are writing a script to be read to an audience Perhaps you can use "and". In this way, you will preserve the original meaning of the sentence. (I guess that our seats were allocated separately and automatically. / I guess that our seats were separately and automatically allocated.) Another example: He was aggressively interrogated intensively (sounds unnatural) He was intensively and aggressively interrogated. (sounds more natural) I hope this helps.

Personally, I wouldn't flag either one as incorrect and I wouldn't say what you'd originally said sounds unnatural either... Honestly, I doubt I would have noticed if you'd said the former, but I suppose if I were saying it myself, I'd likely say "automatically allocated separately". I don't think it's a big deal either way though.

Hi! I think that "automatically allocated separately" sounds the most natural to me, and the most clear. However, I don't think that the first one is incorrect. Maybe it is according to "proper grammar," but if I heard someone say it, it wouldn't sound wrong or strange to me. (I am a native English speaker from the NW USA)

separately allocated automatically To be honest, I don't think that any of those phrases would be incorrect anyway. Follow the little voice inside your head, It's always correct if it sounds natural! At least that's what my intuition tells me.

Good question, meaning "I guess that our seats were (allocated separately) automatically." Or "I guess that our seats were automatically (allocated separately)." I think that if the "allocated separately" is kept together then the meaning is clear. Personally, I would place "automatically" at the front.
