The names themselves
Meaning, roots, sound and the people who carried each
Where each name comes from
Adelynn
noble
The root is Germanic adal, "noble", behind Adela and Adele; the French diminutive -ine gave Adeline, roughly "little noble one". The -lynn spelling is a modern English reshaping of that ending rather than a separate element of meaning.
Adal → Adela → Adèle → Adeline → Adelynn
How it traveled
The oldest layer is the Germanic adal, "noble", which produced Adela and Adele among the Frankish and German nobility of the early Middle Ages. French added its diminutive ending to make Adeline, and Norman speakers carried that form into England after the Conquest, where it stayed in use for centuries before fading and reviving again in the Victorian period.
Mariah
From Hebrew Miryam — most often read as "bitter," "beloved," or "rebellious"
Miryam is one of the oldest genuinely unsettled names in the Bible. The traditional Hebrew reading connects it to a root for bitterness; another long-standing reading gives "rebellious"; a third, favored by many modern scholars, traces it to the Egyptian element mry, "beloved," since Miriam appears in the Exodus narrative in an Egyptian setting. No one reading has won.
Miryam → Mariam → Maria → Mariah
How it traveled
The line begins with Miryam, sister of Moses in the Hebrew Bible, which the Greek translators rendered Mariam and Maria, and Latin carried onward as Maria — the name of Jesus's mother and, through her, one of the most widely given names in the Christian world. English took Maria in and pronounced it muh-RYE-uh, the ordinary reading in the eighteenth and early nineteenth centuries, and Mariah is simply that pronunciation written down.

Out loud, and in short
Adelynn
AD-uh-lin
Stress on the first syllable, with a light final syllable. Adeline is said both AD-uh-line and AD-uh-leen; the -lynn spelling steers people to the -lin ending, which is part of why it exists.
- Addie — The long-standing short form for the whole Adeline–Adelaide–Addison group; also given as a standalone name.
- Addy — Same nickname, spelled to match the double-d of the parent name.
- Lynn — Draws on the back half of the spelling; a full given name in its own right and still common among older generations.
- Ada — Trims to the first syllables; independently used as a formal given name.
- Also Del.
Mariah
muh-RYE-uh
Three syllables with the stress in the middle, which rhymes with "eye." The final h is silent and does the work of signaling that middle sound — Maria without it is usually read muh-REE-uh.
- Mari — The most common short form; also used as a standalone given name in Welsh and Norwegian.
- Ria — Informal, drawn from the end of the name; stands alone as a given name in Dutch and German.
- Riah — Informal, keeps the h of the full spelling.
- Mia — Informal shortening; very well established as an independent name in its own right.
- Also Ree.

The trade-offs, name by name
Adelynn
Strengths
- Addie is an established short form with centuries behind it, shared with Adeline and Adelaide, so a nickname is ready-made.
- The spelling tells English speakers how to say the ending, which the -ine spelling does not.
- Close cousins exist in French, German, Italian, Spanish and Polish, so the name is recognizable well beyond English.
To consider
- Adelyn, Adalyn, Adalynn, Addilyn and Adeline are all in circulation, so this exact spelling will need saying aloud and confirming — on forms, at the doctor's office, in email signatures — for life.
- Taken together, the -lyn names are far more common than any single spelling of them, so a child may well share a playground with an Adalynn or an Evelyn and be told they nearly have the same name.
- The wave behind this spelling is very recent, so it reads as a name of the current moment rather than an inherited one; the underlying Adeline is the version with the long record, if that matters to you.
Mariah
Strengths
- The spelling tells people how to say it: the h steers readers to muh-RYE-uh rather than muh-REE-uh.
- Belongs to one of the largest name families in the world — Maria, Marie, Miriam, Maryam — so relatives in almost any language have a version of it.
- Unbroken presence in American records since the nineteenth century, so it reads as familiar rather than newly coined.
To consider
- One singer has been so closely tied to this spelling since the 1990s that many people will mention her. That association is warm rather than awkward, but it comes up.
- Mariah and Maria will be swapped for each other on forms and in speech for life. Expect to correct both the letter and the vowel fairly often.
- Its strongest years were recent enough that the name currently sits with young adults more than with newborns — a child named Mariah is likely to be the only one in her class while meeting grown women who share it.
