Tips for picking an I name for your son
- Mind the vowel start. Names starting with I can blur into a surname that ends in a vowel (“Ian Adams” can run together), so say the full name out loud.
- Decide on pronunciation early. Ira, Idris and Ivo can each be said a couple of ways; pick one and use it consistently.
- Choose a nickname you love. Ignatius gives you Iggy or Nash; Isaac gives you Ike; Isaiah often becomes Zay.
- Explore heritage. Welsh (Iolo, Iorwerth), Igbo (Ikenna, Ifeanyi) and Japanese (Isamu, Itsuki) I names honor a family’s roots — see more in our Nigerian boy names.
- Pair with a grounding middle name. A short I name like Ivo or Ira works beautifully with a longer middle, and vice versa.
