The word "mighty" has a strong connotation about Beowulf. It is a connotative word because it relates to the context. Without the context, it wouldn't be clear what it actually means. In this case, it means that Beowulf is known to be brave and widely honored. The word "sensible" has a strong connotation about Beowulf's chosen warriors. It means that they are afraid of the journey's outcome, but they nevertheless keep their opinions to themselves. They kept silent "though he was dear to them" - although they anticipate that something bad might happen.
