When communicating either in speech or writing, it's crucial to have a varied lexicon to avoid repetition and monotony. There are multiple synonyms for "stay with," some of which include, remain, linger, abide, continue, stick around, endure, hold on, persist, and lodge. Depending on the context of the message, utilizing any of the synonyms would add flair and sophistication to the composition. For instance, instead of saying, "I'll stay with you until the end," one can say, "I'll abide with you till the very last moment." Finally, using synonyms enhances communication and provides a robust vocabulary.
