Two hundred seven words begin with O, and the second box spreads wider here than on almost any other letter.

A Very Flat Spread After O

R leads the second box on just twenty seven words, thirteen percent, with U on seventeen, L on sixteen and C on thirteen. Twenty three different letters appear there in total.

No branch reaches even a seventh of the page. That makes the second box the worst place to spend an opening guess on this letter.

The O Words Worth Knowing

OTHER, OCEAN, ORDER, OFFER and OUGHT are the entries a puzzle is most likely to want, with OPERA, ONION and OLIVE behind them.

The Doubled Letter Habit in O Words

Twenty three of the two hundred seven repeat a letter, eleven percent. OFFER, OTTER and ODDLY are the shapes behind most of it.

That is low enough that a visible double is a real signal here rather than background noise, which is not true of every letter.

What an O Guess Actually Tells You

E fills the fourth box in fifty four of the two hundred seven, twenty six percent, the single strongest fact on the page, and S closes fifty words. So work the back of the word first. OTHER tests the E fourth box and the R ending together, which covers more than any second letter guess could.

Frequently Asked Questions

Is OTHER the best O opening

Yes. It is the most common word here and it tests the two most reliable boxes at once.

Why is the second box so unhelpful

Twenty three letters appear there and the leader takes only thirteen percent. No guess aimed at that box removes much of the page.

How many O words end in S

Fifty, which is twenty four percent. E and R follow on twenty six and twenty four.
