Bailey's Wave Model uses which central metaphor for language change?

• A. A drop of water creating ripples on a lake
• B. A straight line extending across regions
• C. A tree growing in a forest
• D. A spiral staircase of change

Answer: (A)

Diffusion of language change through a speech community is tested here. Bailey's Wave Model uses the drop of water creating ripples on a lake as its central metaphor. It shows how a change originates at a central point and radiates outward, influencing nearby speakers first and gradually reaching farther areas. This conveys how adoption varies with distance and social contact, with the strongest influence near the source and attenuating as it spreads. Other options don’t fit as well because a straight line implies uniform, unidirectional spread; a tree suggests a genealogical branching of features rather than diffusion across space; and a spiral staircase implies a single, cumulative path rather than multi-directional diffusion through networks.
