The pattern is unusually narrow: only 31 tournament-dictionary entries put D in position two. Most start with A, while nearly all finish with S. The vocabulary ranges from familiar word-building forms such as administrations to specialist terms such as adenohypophyses, and just one entry falls within the top 25,000 English words by frequency, so expect a specialist-heavy set rather than everyday vocabulary.

How many 15-letter words with D as the 2nd letter?

  • The pattern matches 31 words in at least one tournament dictionary.
  • A begins 16 entries; I begins eight, E begins four, and O begins three.
  • Twenty-seven entries end in S, while Y appears at the end of two.
  • Collins includes all 31; ENABLE and NWL2023 each include 17.
  • Only one entry ranks among the top 25,000 English words by frequency.

Why do so many end in S?

The ending is the clearest shortcut: 27 of the 31 words finish with S. Administrations, identifications, educationalists, and adenocarcinomas all fit that pattern, making a known final S a strong clue rather than a coincidence.

The opening letters narrow the search further. Administrations and adventurousness start with A; identifications and ideographically start with I. By comparison, only four entries start with E, including edriophthalmian and edriophthalmous, so a second-letter D does not imply a single familiar prefix.

Which entries make the strongest Scrabble plays?

Adenohypophyses and adenohypophysis lead the scoring table at 32 points each before board premiums. Idiomorphically scores 28, while ideographically and odontorhynchous each score 27. These are substantial tile scores, but their specialist vocabulary makes them risky plays unless you know your game’s dictionary.

The 15-letter words with D as the 2nd letter are not evenly shared across word lists: Collins accepts the full set, but ENABLE and NWL2023 each accept only 17. For a more practical search, start with administrations or identifications, then confirm the exact spelling and your game's dictionary.

Questions people ask

Are all 31 words accepted in NWL2023?
No, NWL2023 includes 17 of the 31 matching entries. Collins includes all 31, so acceptance depends on the word list used in your game. Check the game’s dictionary before playing a less familiar term such as adenohypophyses.
Which letters begin words with D as the second letter?
A is the most common first letter, starting 16 entries; I starts eight. E starts four and O starts three. Examples include administrations, identifications, edriophthalmian, and odontorhynchous.
How many of these words have definitions?
Sixteen entries have definitions. The set includes recognizable forms such as administrations alongside technical terms such as adenohypophyses, so having a definition does not necessarily mean a word is common in everyday writing.
