There are greater possibilities for a language utterance to have more meanings than what is stated. It is also possible for the hearers/audience to interpret what the speaker has in mind beyond what the speaker has put out in words. These meanings derived in this form are echoic and they are arrived at by choosing meanings that contextually relevant involving the least effort. How echoic relevant definitions are achieved has been studied using different language instances. Still, none in the researchers' knowledge has investigated how the COVID 19 social media memes, as used by Nigerians, communicate deeper meanings that are contextually relevant and how the echoic interpretations reveal the users' attitude. On this basis, therefore, the present study investigated the echoic nature of COVID 19 related social media memes as used by Nigerians. The study used Sperber and Wilson (1986) relevance theory as the theoretical framework and qualitatively analyzed Ten (10) purposefully selected memes. In the end, the study found out that interpretations of memes are significantly linked with the shared cognitive background knowledge which the speaker/meme creator and the hearer/audience have. Also, memes could echo the attitude of concern, disdain and fear while also harboring deeper meanings that contextually relevant and implicit.
