Meaning by written form
What can Sei mean?
A Japanese name can be written in more than one way, and its meaning can change with the kanji used. Rather than assigning one English meaning to “Sei”, this page explains each recorded spelling separately.

Kana-only spelling
セイ
This spelling is written only in kana. Because it contains no kanji, there is no kanji meaning to interpret here. The kana record the name’s sound; any personal or cultural meaning would depend on context not supplied by the dictionary.

JMnedict classification evidence
How this reading is classified in the source corpus
This separates dictionary classification from popularity. The same exact kana reading can be recorded as a given name, a surname, or both, and given-name records can carry male, female or unspecified source labels.

row counts carrying each JMnedict source label
| Exact reading | Given-name evidence | Given-name labels | Surname evidence |

Classification boundary: male/female/unspecified are labels attached to imported JMnedict name records. They are not population shares, probabilities, identity claims, or evidence that a spelling is currently common in Japan. A source row can also be repeated across different written forms, so row counts and distinct-writing counts are shown separately.
JMnedict source text
Source-supplied text attached to Sei records
JMnedict can attach trans_det text to a name-classification block. This may be a Latin spelling, label or descriptor. It is shown only when it adds information beyond this site’s generated romanization.
| Written form | Source reading | JMnedict source text |
|---|---|---|
| セイ | せい | Say |
| セイ | せい | See |
Meaning boundary: this is text supplied by JMnedict for the associated name-classification block. It is not an inferred kanji meaning, a translation of the written characters as a whole, proof of a person’s preferred Latin spelling, or evidence of popularity.
38 source-text items were omitted because they are equivalent to the generated romanization and would add no distinct information.

Reading ambiguity
Can the same writing be read another way?
26 of 38 displayed written forms have more than one given-name reading somewhere in the active JMnedict corpus. This is dictionary-record ambiguity, not a prediction of how a particular person reads the name.

Kanji role reference
How recurring characters function across Sei spellings
Position counts are calculated only from the distinct written forms analyzed for this page. KANJIDIC2 nanori are character-level name-reading references; they are not used here to decompose or assert the reading of a specific multi-kanji name.

These relationships are exact and source-backed. Whole-name readings shown in each card come from JMnedict within the current name class; exact-writing search can surface records from other name classes. Character links open KANJIDIC2-backed kanji pages. Sequence context means the same kanji string occurs contiguously in another recorded written form—it does not prove shared origin or meaning.

What does Sei mean?
There is not necessarily one fixed English meaning. The reading identifies the spoken name; different written forms can use different kanji. Character glosses describe individual kanji and should not be treated as proof of the intention behind a particular person’s name.

What each source establishes
JMnedict establishes recorded written forms, readings and name classifications; where safely associated, this page can also show JMnedict-supplied trans_det source text without treating it as a whole-name meaning. KANJIDIC2 supplies character readings, nanori, stroke counts, grade classes and English character glosses. The Ministry of Justice remains the official reference for Japanese child-name character rules. The Agency for Cultural Affairs romanization guidance is the reference for generated Latin-script reading aids.
Source boundary
The spelling-frequency and structural counts on this page are calculated from imported JMnedict records. They are corpus counts, not population-frequency claims. KANJIDIC2 supplies the kanji metadata used in character and stroke comparisons.
