The word "was session" is not a correct phrase in English. However, the correct spelling of the individual words is "was" /wʌz/ and "session" /ˈsɛʃən/. "Was" is the past tense form of the verb "be" and is pronounced with a short vowel sound followed by a voiced consonant. "Session" refers to a period of time devoted to a particular activity and is pronounced with a stress on the first syllable and a sh sound in the second syllable.
"Was session" is not a widely recognized term in English. Therefore, there is no known dictionary definition specifically for this term. Nonetheless, "was" is the past tense of the verb "to be," while "session" typically refers to a meeting, conference, or period of activity dedicated to a specific purpose. Based on the limited information available, one possible interpretation of "was session" could be a term used to describe a meeting or event that has already taken place in the past, hence the use of the past tense. For example, an individual might say, "Yesterday, we had a session. It was a session." In this context, "was session" could refer to reflecting upon or recalling a prior meeting or gathering.
However, without further context or clarification, it is difficult to precisely define the term "was session." It is possible that the term could have a different meaning specific to a particular field, organization, or dialect. If this is the case, it would be necessary to provide more information in order to formulate an accurate definition.
