20d. What's numbered 14 – 14 as source of strength (6). I have – I – E – S. 14, which is referenced in several clues, is WORD FOR WORD. I'm wondering about SINEWS for the strength, but can't parse it. It's my last one.
Thanks. At least I guessed right. The Silicon bit is brilliant, but I think the News part is a stretch.
One thing I hate about this site is that it classifies questions differently for slight changes in presentation, such as whether you have a comma in the puzzle number. I feel such a fool asking a question that has already been asked, even though I had searched for other answers.
