  • Lesson 5 • Verb Agreement and Directionality

    Introduces spatial grammar where verb movement encodes subject and object. Students produce agreeing verbs accurately in two- and three-person contexts.

Chapter 4See details

Non-Manual Markers and Prosody

  • Lesson 1 • Facial Grammar Fundamentals

    Identifies the grammatical roles of eyebrows, eyes, and mouth in signed sentences. Distinguishes grammatical facial expressions from emotional ones.

  • Lesson 2 • Body Posture and Role Shifting

    Teaches how body lean and shoulder shift indicate character or perspective changes. Enables students to portray multiple characters in a single narrative.

  • Lesson 3 • Intensity and Degree Modulation

    Shows how movement size, speed, and facial intensity modify adjective and verb meaning. Students express degree without additional lexical signs.

  • Lesson 4 • Prosody and Phrasing in Signing

    Covers pausing, rhythm, and phrasing that make signing natural and readable. Connects prosodic control to comprehension by Deaf interlocutors.

  • Lesson 5 • Locating Objects in Signing Space

    Teaches how to establish and maintain object locations in three-dimensional space. Enables accurate spatial descriptions of scenes and layouts.

Chapter 6See details

Receptive Skills and Comprehension
