Othar, of Germanic origin, translates to 'great'. It was once widely used among the Saxons and is now more commonly found in Scandinavia, particularly Denmark, where it has a distinct historical presence. The name is unique yet not unfamiliar, carrying an air of nobility and robustness associated with its meaning. Othar is composed of two elements: 'oth', which means 'wealth' or 'prosperity', and 'harja', meaning 'army'. Thus, the name could be interpreted as signifying 'prosperous in battle'. However, its usage has extended beyond these historical contexts, making it a notable yet approachable choice for parents seeking an uncommon yet significant name for their child. Spelling variations include Otharius and Otharich, with Othmar being a close variant.
The name Othar experienced fluctuations in popularity from 1914 to 1936, with the highest number of births occurring in 1922 (9 births). However, it appears that the name's popularity waned over time, as indicated by a decline in birth counts after the mid-1920s. The total number of births recorded during this period was 97.
