In the context of antonyms, the most suitable words that can be used in place of obtainings are "losing," "giving away," "surrendering," "forfeiting," or "relinquishing." These words represent the opposite of obtaining as they imply the act of giving up or losing something rather than acquiring it.

Similarly, the act of surrendering or forfeiting something denotes that one is losing their possession or ownership of it, which is the opposite of obtaining.
