Terminal: run. Derivation Graphs: (left-to-right) compact / full; (top-down) full / compact.
Help: blue = parse inside. Abbr.: WS: Workspace; Initial WS: initial heads for Merge after LEX lookup.
- WS n, n = 1,2,... for intermediate stages after Initial WS. Final WS: when WS items converge on a single SO.
- Bracketing: {...} (Merge). {...} (FormSet). At Spellout, {...} indicates free word order. [word] indicates word is optionally present.
- Head Hdselection/features, e.g. pθ = predicate head p that seeks a θ-relevant (θR) IA from the WS. pθ is a θ-seeker (θS).
- vsee:θ:pst = head v has complement see, a θR EA from the WS and TNS. v is also a θS.
- INFL seeks θR from its complement (not the WS).
- Complementizer C comes in different flavors wrt. Force, .e.g. declarative C, interrogative CQ and relative clause head Crel.
- Features, e.g. TNS pres/pst or DET the/a (shorthand for a bundle of semantic features).
- Note: φ-features, e.g. 1sg, appear only at Spellout. Some words do not project, turn into features, e.g. determiners.
