Only seven words start with IS, and the fourth box is an E in most of them.
L takes it in three of the seven and S in two, with B and T on one each. With a page this short, that single letter separates most of the list.
ISSUE is the one entry anyone would produce without prompting. ISLES and ISLET follow and both are reachable.
ISBAS, ISLED, ISSEI and ISTLE make up the rest. An isba is a log hut, an issei a first generation immigrant, and istle a plant fibre, so none is vocabulary you carry.
E fills the fourth box in four of the seven, fifty seven percent, which is the only distribution here with real weight.
Both words carry an S nobody pronounces, which is why players scanning by sound tend to miss them. ISLED does the same thing.
That makes the L branch easy to overlook even though it is the largest one on the page.
With seven entries there is no branch structure to work through. Compare the list against whatever boxes your puzzle has confirmed and play the one that fits.
On this page it usually is, since it is the only entry in general use. ISLET is the realistic alternative.
Only in the last box, and ISLED sits on the same stem. All three carry the silent S.
A first generation Japanese immigrant. It is one of two words here that repeat a letter.
