Inauspiciously is how something happens when the first moments already look unlucky or poorly timed. A meeting that begins inauspiciously might start with a power cut; a plan that launches inauspiciously might hit a delay on day one. It is the adverb of inauspicious, so it tells you about the manner of the start, not the name of the thing. The word is formal. You will find it in writing more than in the cafeteria. Friends would more often say it started badly, or it was not a good beginning. Though actually, it still does not mean the ending is fixed. An inauspicious beginning is a feeling and a first picture, not a verdict. People use it when they want a little drama and a little distance — to name the bad start without shouting that everything is ruined.
