To have some or certain hesitations, apprehensions, uneasiness, or pangs of conscience (about something or someone). (Also often used in the negative to mean the opposite.) I know it's wrong to feel this way, but I don't have any qualms about telling my boss I'm sick if it means I can have a long weekend. I thought his promotion was a done deal, but it turns out the board of directors has some qualms about Jonathan. Before we start, do you have any qualms about the plan we discussed?

To cause one to feel some or certain hesitations, apprehensions, uneasiness, or pangs of conscience (about something or someone). Lying always causes me qualms, so I doubt I'll be able to tell my boss that I'm sick just to get a long weekend. I thought Jonathan's promotion was a done deal, but his latest interview seems to have caused the board of directors some qualms.
