addition A₁D₂D₂I₁T₁I₁O₁N₁

Most people meet addition in arithmetic, but the word has a second everyday sense and a specialized musical one. Its eight letters also make a modest Scrabble score: the two Ds account for four points, and every other tile is worth one. Audition is its sole one-letter neighbour, while rearranging all the letters yields no anagrams.

Addition meaning, score and spelling at a glance

• Addition has eight letters and scores 10 points in standard Scrabble tile values.
• It means either the act of adding or something that has been added.
• In music, a dot after a note lengthens its sound by one-half.
• Audition is the only one-letter neighbour; there are no anagrams.

What does addition mean?

The main addition meaning is the act of adding: the arithmetic operation that combines quantities into a total. The same noun also names the thing added, such as an extra item or amount. Those two uses are closely related, but one names an action and the other its result.

A less familiar definition comes from music notation. A dot placed to the right of a note lengthens its sound by half; in that context, addition refers to the marking or added duration. This specialized sense is easy to miss if you know the word only from arithmetic.

How does addition score, and what can you make from it?

Addition earns 10 points before any board-square bonuses. Its tiles total 1 + 2 + 2 + 1 + 1 + 1 + 1 + 1: the pair of Ds contributes four points, while the six remaining tiles contribute one each. The duplicate D is the scoring detail to notice; the rest of the rack is low-value.

No anagrams are listed, so rearranging all eight letters does not produce another word in the available word lists. Audition is the sole one-letter neighbour, changing the opening A to U. That close spelling makes it a useful comparison when checking a word by letter pattern.

For sound-based clues, addition shares its final -tion sound with information, question, million, action and decision. There are 12 listed rhymes in all, including education and union. The word is common in ordinary English, but its rhyme family is much larger than its set of one-letter neighbours.
