38 in words: Thirty-eight
To write thirty-eight you work from the largest value down: XXX (30) + VIII (8). Set each group in turn, left to right, and stop when there is nothing left over. That gives XXXVIII.
There is no subtraction to handle here, so every group in XXXVIII simply adds on. Numerals like this are the ones to practise on before you tackle the subtractive forms such as IV and IX.
What XXXVIII means, letter by letter
XXXVIII is 38, "thirty-eight". It is built from XXX (30) and VIII (8), read from the largest value down and added together. Every symbol here is added in sequence, with no subtraction involved.
To read XXXVIII back, scan it left to right, largest value first, adding as you go. The running total lands on 38:
| Read | Worth | Running total |
|---|---|---|
| XXX | 30 | 30 |
| VIII | 8 | 38 |
There is no subtraction anywhere in XXXVIII, so every letter simply adds to the total: no letter changes the meaning of the one next to it. Read aloud, XXXVIII is simply "thirty-eight".
Write XXXVIII step by step
The rule is always the same: take the largest Roman value that still fits, write its symbol, subtract it, and repeat until nothing is left over. Applied to 38 that gives 7 steps.
| Step | Take | Write | Numeral so far | Left to write |
|---|---|---|---|---|
| 1 | 10 | X | X | 28 |
| 2 | 10 | X | XX | 18 |
| 3 | 10 | X | XXX | 8 |
| 4 | 5 | V | XXXV | 3 |
| 5 | 1 | I | XXXVI | 2 |
| 6 | 1 | I | XXXVII | 1 |
| 7 | 1 | I | XXXVIII | 0 |
Nothing is left over after step 7, so the finished numeral is XXXVIII. Written out in English words that is "Thirty-eight".
Forms to avoid when writing 38
These are the spellings people reach for instead, and why each one is wrong for 38.
- Not XXXXVIII. X already appears three times in XXXVIII, which is the maximum. A fourth X is never valid, so if you need more you move up to the next symbol instead.
- Not XXXVVIII. V never repeats. Two of them would simply be the next symbol up, so a doubled V is not a numeral at all.
Check XXXVIII reads back as 38
Writing a numeral and verifying it are two different jobs, and the second one is what saves you on anything permanent. Read XXXVIII back left to right, adding each group and treating any smaller-before-larger pair as a single subtraction. If you land on 38, the numeral is correct. The converter above does exactly this and refuses any non-standard spelling, so a value it accepts is a value you can use.
