6-letter words with I as the 1st letter and G as the 3rd letter

One word breaks the rule and the rest obey it. Only IGGING avoids the ING- opening, so the pattern reads as a single family with a single stray. Scores stay tiny, topping out at 10, and Collins is the one tournament list that carries all 12.

Six-letter words with I as the 1st letter and G as the 3rd letter

• Twelve matches, and 11 of them open ING-.
• IGGING is the only word that starts any other way.
• INGULF tops the scores at 10, the flattest ceiling in any I-first frame.
• Collins holds all 12, but NWL2023 takes six and ENABLE only five.
• INGRAM is the lone common word.

The ING- family and its stray

IGGING is the outlier, a doubled-G form that keeps G in the third slot without the usual opening. Everything else follows the same three letters: INGRAM, INGEST, INGOTS, INGLES, INGULF, INGOES, INGANS, INGATE, INGENU, INGINE and INGRUM.

That gives the list a rhythm, because a clue yielding I-N-G has already handed you three letters of six. INGEST and INGOTS are the two most recognisable, while INGINE and INGENU rarely leave a dictionary. Three letters of six from a single clue is why this shape reads as friendly even though the words are rare.

Why the scores never pass 10

The average sits at 7.8 and INGULF is the ceiling at 10, lifted by its F alone. IGGING, INGRAM and INGRUM follow on nine, and the remaining eight words all tie on exactly seven, which leaves the list with almost no spread.

The dictionary split is the real story. Collins keeps all 12, NWL2023 keeps six and ENABLE five, so half the list drops out the moment you move from a Collins board to a North American one, and the survivors are mostly the ING- words everyone already knows.
