The words ‘aver’ and ‘avow’ are verbs and can be tricky to comprehend and use owing to the similarity in their meaning. ‘Aver’ is composed of Latin ‘ad’ and ‘verus’, meaning ‘to’ and true’ respectively. Hence, ‘to aver’ means to declare or assert the truth. It means to affirm a fact about something with absolute confidence. Avow, on the other hand, descends from Anglo-French ‘avouer’ meaning ‘to acknowledge or recognize as a matter of fact’. It means to publicly and openly proclaim something as a believed truth. It also means to take a vow or promise something. Simply-put, aver means to acknowledge, while avow means to declare.

Definition of avow

Avow is pronounced as ‘ay-vau’ and used as a verb. It is often used transitively, literally meaning to ‘to take a vow’. ‘Avow’ basically means to assuredly express something frankly and publicly, usually under an assumed or literal pledge. It is used in both formal and legal discourse and has a slight overlap in the meaning in the respective contexts. Legally, it denotes the action of publicly, openly declaring something as a matter of fact. For example ‘criminals avow their crimes in court regularly.’

The word has also found its use in situations of open declaration or private assurances. For instance, a mayor may ‘avow’ to avenge the deaths of his city’s citizens; where the verb stresses on his ‘public promise’. Similarly, a couple may ‘avow’ to love each other till death separates them; where the verb carries a sense of a ‘private pledge’.

It must be understood, however, that the subject does not need to make a literal promise or be under a literal oath or pledge. The word shows that the subject is under an obligation (pledge) and he willfully wants to follow it. Simply put, ‘avow’ carries the elements of assertive declaration and personal responsibility, unlike ‘aver’ which lacks the latter quality. Synonyms of ‘avow’ include ‘swear’, ‘avouch’, and ‘declare’. Present participle of ‘avow’ is ‘avowing’ while past participle are ‘avowed’.

Example sentences of avow

  • It is a hallmark of dictatorships that opponents who refuse to avow their loyalty to the premier, often disappear.

Conclusion

The words ‘aver’ and ‘avow’ certainly seem to have an apparent overlap in their meanings. However, with little consideration, you can learn to use the proper verb for any sentence. It is noteworthy that both of these verbs refer to a declaration or affirmation of truth. However, it must be remembered that aver is typically used to confirm the truth while avow can be used in several other senses including the declaration of a promise. Additionally, ‘avow’ carries the sense of personal responsibility or duty while ‘aver’ does not.

For prompt use, remember that ‘aver’ has ‘-ver’ in it and so does ‘verify. So ‘aver’ can be used wherever an object demands to be verified. Similarly, ‘avow’ has ‘-vow’ in it, which means promise, which demands subjective accountability. Hence, wherever the subject is to be held responsible for his words, especially on a public or legal forum, the proper verb to be used is ‘avow’.
