Ok, now you know what the name Adair means, the next question is, is it definitely the right first name for your infant? Thinking up a name for your baby is perhaps the most life-changing decision you will make for them, and you will probably spend days, or even longer, wondering whether Adair is a suitable first name for your baby. As we have already explained, Adair is Celtic originally, and so the first thing you need to consider is whether this Celtic first name is practical for your newborn - if you are particularly close to Celtic culture, then choosing a distinctive Celtic name for your baby is in all probability right and proper. If not, then you will need to weigh up the impact of leaving your little cherub with a name that stands out too much and may well cause problems in school and even later in their life. Thinking up a unique Celtic name for your infant may help or hinder them - so if you are not sure, then picking a popular name for your baby might be a more desirable choice instead.
