Languages that are typically distinct find a common link in summer. While Romance and Baltic languages often differ, they share the P.I.E *wósr̥, "spring" and originally "becoming warmer." Portuguese "verão" and Latvian "vasara". Similarly, the German "Sommer" and Finnish "kesä," despite their different appearances, both stem from the P.I.E root *semh₂-, "summer or half of the year."
