6-letter words with A as the 1st letter and U as the 2nd letter

The fixed AU opening gives you a narrow six-letter search, but the entries range from familiar words such as AUGUST and AUTHOR to specialist terms such as AUSPEX. Just 8 of the 43 qualify as common by the frequency measure used here. Dictionary totals differ too, so a game’s accepted list matters as much as the spelling pattern.

6-letter words with A first and U second at a glance

• Exactly 43 six-letter entries begin AU across the tournament dictionaries counted here.
• Only 8 rank among the top 25,000 English words by wordfreq frequency.
• Collins includes 41, NWL2023 includes 38, and ENABLE includes 34.
• Final S is the leading ending: 12 entries end that way.
• AUGUST, AUTHOR, AUTUMN, and AURORA are recognizable examples.

Which familiar words fit the AU pattern?

Among familiar entries, AUGUST names a month, AUTHOR a writer, and AUTUMN a season; AURORA is another recognizable choice. The shared AU opening narrows the search sharply, but the third letter separates ordinary vocabulary from specialist terms.

Only 43 entries meet both fixed positions, compared with 226 six-letter words beginning BU and keeping U second. If you know just the first two letters, this is a compact branch; if another tile is fixed, use that clue before guessing obscure endings. AUBURN and AUNTIE offer further everyday anchors, while AUGURY is less familiar but easy to spot once the prefix is fixed.

AUSPEX leads the scoring list

Endings are not evenly spread: 12 words finish in S, while E and T each close 5. That makes an S-ending a sensible branch to inspect first, but it still accounts for less than a third of the set. AUTHOR ends in R, while AUGUST ends in T, giving two familiar routes through the pattern.

On the Scrabble score list, AUSPEX leads at 15 points; AUXINS and AUMBRY each score 13. The winner is not the most familiar entry, so do not confuse a high tile total with a likely everyday answer. AU gives little room to exploit high-value opening letters, making the final four tiles matter more.

Dictionary coverage also differs: Collins accepts 41 entries, NWL2023 38, and ENABLE 34. The combined count does not mean every game accepts every word. Check your game's word list before playing an unfamiliar form such as AUSPEX.
