How deep should a tree be?

• Is there a principle in branching

• When should the constituent give rise to children?

• What is the hierarchy building principle?

Deeper trees needed for capturing sentence structure

“Constituency test of Replacement” runs into problems

• One-replacement:– I bought the big [book of poems with the blue

cover] not the small [one]– One-replacement targets book of poems with

the blue cover

• Another one-replacement:– I bought the big [book of poems] with the blue

cover not the small [one] with the red cover– One-replacement targets book of poems

Bar-level projections

• Add intermediate structures– NP (D) N’– N’ (AP) N’ | N’ (PP) | N (PP)

• () indicates optionality

Arguments and Adjuncts

Rules in bar notation: Noun

• NP (D) N’

• N’ (AP) N’

• N’ N’ (PP)

• N’ N (PP)

Rules in bar notation: Verb

• VP V’

• V’ V’ (PP)

• V’ V (NP)

Rules in bar notation: Adjective

• A’ (AP) A’

• A’ A (PP)

Rules in bar notation: Preposition

• PP P’

• P’ P’ (PP)

• P’ P (NP)

Introducing the “X factor”

• Let X stand for any category N, V, A, P

• Let XP stand for NP, VP, AP and PP

• Let X’ stand for N’, V’, A’ and P’

XP to X’

• Collect the first level rules– NP (D) N’– VP V’– AP A’– PP P’

• And produce– XP (YP) X’

X’ to X’

• Collect the 2nd level rules– N’ (AP) N’ or N’ (PP)– V’ V’ (PP)– A’ (AP) A’– P’ P’ (PP)

• And produce– X’ (ZP) X’ or X (ZP)

X’ to X

• Collect the 3rd level rules– N’ N (PP)– V’ V (NP)– A’ A (PP)– P’ P (NP)

• And produce– X’ X (WP)

Basic observations about X and X’

• X’ X (WP)

• X’ X’ (ZP)

• X is called Head

• Phrases must have Heads: Headedness property

• Category of XP and X must match: Endocentricity

Basic observations about X and X’

• X’ X (WP)

• X’ X’ (ZP)

• Sisters of X are complements– Roughly correspond to objects

• Sisters of X’ are Adjuncts– PPs and Adjectives are typical adjuncts

• We have adjunct rules and complement rules
