Many baby name websites feature well-researched, reliable information. Many others, though, do not. Those in the latter group tend to offer definitions that are short, vague, and often inaccurate. For example, here are some not-so-great definitions I've seen online recently:

• Aquila - "eagle-eyed" in Spanish
  Aquila is simply the Latin word for "eagle." Here, though, its definition has been fancifully expanded to mean something quite different.



• Clyde - "river" in Scottish
  The River Clyde exists, and it's located in Scotland, but Clyde is not the Scottish word for river. (In fact, no one is exactly sure what Clyde means.)



• Dara - "wealthy" in Persian
  This definition is correct but incomplete, as Dara can also mean other things in other languages (e.g., "compassion" in Hebrew, "oak tree" in Irish).



• Forbes - "prosperous" in English
  The magazine 'Forbes' definitely caters to a "prosperous" crowd, but the name Forbes actually comes from the Gaelic word for field, forba.



• January - "born in January" in English
  January refers to the Roman god Janus, not to babies born during the first month of the year. (This is not the definition of January, but a possible interpretation of January as a name.)



• Knut - "respectable" in Danish
  I'm not sure where this association came from, but the meaning of Knut is straightforward: it comes from the Old Norse word knutr, meaning "knot."



• Norma - "model" in English
  Marilyn Monroe may have boosted the popularity of the name Norma, but Norma doesn't mean "model" now as a result. In fact, Norma may simply be a literary creation (from Alexandre Soumet's 1831 play Norma).



• Tanya - "fairy princess" in Russian
  The Roman family name Tatius, from which Tanya (via Tatiana) is ultimately derived, has no known meaning. (My best guess is that "fairy princess" refers to the late Grand Duchess Tatiana of Russia.)

...So how can you be sure you really know what your favorite names mean? By employing these three tips:

Dig deep. Never settle for a two- or three-word definition. Try to trace each name back to its origin and research how it evolved over time.

Consult many sources, both online and off. You may even want to verify certain facts using non-name-related references, such as multi-language dictionaries.

Be critical of everything you read, as even reliable sources can sometimes be incorrect. For each definition, ask yourself questions like: "Does this make sense?" and "Is this giving me the full picture of the name?"
