Narrative:

While on the ILS approach to runway 27L at ord, inside the OM., we were advised by ord tower of a windshear report by a previous aircraft and, I believe, he may have mentioned a previous microburst alert, rather than a current one. (My first officer's recollection was a windshear alert, not a microburst alert.) on that basis, we continued our approach and landed as cleared. Our experience throughout the approach was speed fluctuations not exceeding +/-5 KTS. A normal landing and rollout followed. I'm submitting this report because, in hindsight, I have a nagging concern that I may have misunderstood the tower and perhaps should have made a missed approach. While my workload at the time was rather high, as the PF, I feel I should have pushed harder for clarification. (Communications confusion.)

Title: WDB CREW WAS GIVEN WINDSHEAR WARNINGS WHILE ON FINAL AT ORD.

Narrative: WHILE ON THE ILS APCH TO RWY 27L AT ORD, INSIDE THE OM., WE WERE ADVISED BY ORD TWR OF A WINDSHEAR RPT BY A PREVIOUS ACFT AND, I BELIEVE, HE MAY HAVE MENTIONED A PREVIOUS MICROBURST ALERT, RATHER THAN A CURRENT ONE. (MY FO'S RECOLLECTION WAS A WINDSHEAR ALERT, NOT A MICROBURST ALERT.) ON THAT BASIS, WE CONTINUED OUR APCH AND LANDED AS CLRED. OUR EXPERIENCE THROUGHOUT THE APCH WAS SPD FLUCTUATIONS NOT EXCEEDING +/-5 KTS. A NORMAL LNDG AND ROLLOUT FOLLOWED. I'M SUBMITTING THIS RPT BECAUSE, IN HINDSIGHT, I HAVE A NAGGING CONCERN THAT I MAY HAVE MISUNDERSTOOD THE TWR AND PERHAPS SHOULD HAVE MADE A MISSED APCH. WHILE MY WORKLOAD AT THE TIME WAS RATHER HIGH, AS THE PF, I FEEL I SHOULD HAVE PUSHED HARDER FOR CLARIFICATION. (COMS CONFUSION.)
