This tree appears to me to be malformed. Does anyone really think [PP by [DP itself]] is a valid *complement* of the Npressure? I see no reason to postulate that pressure c-commands by itself. PPby in this case appears to express verbal manner semantics, usually construed as an adjunct to a VP, vP or TP/IP. Also worth questioning the grammaticality of the entire phrase "the window broke from the pressure by itself". 73.219.15.198 (talk) 18:29, 23 December 2021 (UTC) an interested linguist
