buzzword

باللغة العربية: كَلِمَة طَنَّانَة، مُصْطَلَح شَائِع

1. A word drawn from, or imitative of, technical jargon, used more to impress others than to convey meaning. · Their salespeople know all the right buzzwords, but they can't really help you solve your problems.
2. A little-known word used to sound scholarly or professional, or to flaunt one's vocabulary. · Why not just say "compare" instead of "juxtapose"? No one understands you when you use these buzzwords.
