breakthroughs
- 1Plural of breakthrough.
A string of scientific breakthroughs reshaped the entire field within a decade.

Note
Only the noun takes the -s. When the word stands before another noun, it stays singular. A lab reports several breakthroughs but publishes breakthrough results, and doctors speak of breakthrough symptoms that appear despite treatment, never breakthroughs symptoms. The plural covers every field the singular does: armies pushing past enemy lines, tunnels meeting from both ends, and discoveries that clear a major obstacle.
