She see a men. � Morphology: analysis of word forms • Synatx: acceptable � Synatx: She sees a man. analysis of structure She sees the men. � Semantics: analysis of meaning ..................... 7 8 2
11/16/2012 Semantics Semantics • Syntax: acceptable • We need structures to model sentences, phrases and words. Colorless green ideas sleep furiously. • The spatial markers ‘in’, ‘on’, par , sE etc. are not mere atomic labels, but they are However, the sentence is (usually) not modeled by using complex structures. acceptable semantically. 9 10 Polysemy • It is the capacity for a word to have Representation of multiple related meanings. Spatial Markers e.g. crane (a bird, a machine) • It is distinct from homonymy , in which the multiple meanings of a word my be unconnected or unrelated. e.g. bark (dog’s, wood’s) 11 3

11/16/2012 Jackendoff (1990) Examples • in the box • Conceptual Structures � ‘IN’ : [ Place IN ([ Thing ])] ‘IN’ : [ Place IN ([ Thing box])] � ‘From’ : [ Path FROM ([ Place/Thing ]) ] • from the market � ‘Through’ : [ Path VIA ([ Place/Thing ]) ] ‘From’ : [ Path FROM ([ Place market]) ] � ‘To’ : [ Path TO ([ Place/Thing ]) ] • mEz taaN (‘off the table’) <Sindhi> [ Path FROM ([ Place ON ([ Thing table]) ]) ] 17 18 Kracht (2002) Modes for spatial markers • Locative expressions have two layers: • coinitial (object moves away from location) e.g. configuration and mode . ‘from’ • The configuration is the way in which several • transitional (object enters and leaves the objects are positioned with respect to each location) e.g. ‘through’ other. � Examples are: ‘at’, ‘in’, ‘on’, ‘between’, ‘in front’ etc. • cofinal (object reaches the location) e.g. ‘to’ • The mode describes the way in which an object moves with respect to the named configuration. • static (object is at the location) e.g. ‘at’, ‘in’ 19 20 5

South Asian Spatial markers • Features (source and goal) � source : [+source,-goal] • Spatial Usages � path : [+source,+goal] • Non-spatial Usages � location/goal : [-source,+goal] � theme : [-source,-goal] 21 PhD Dissertation Dissertation Questions • Dissertation Title: Spatial Expressions and Case • Question 1: Did many case markers originate in South Asian languages . from spatial terms? • Question 2: Can a model be proposed that explains different spatial usages of the same • Supervisor: Miriam Butt form? • Question 3: Why is a core spatial marker used • Major work was done as part of the project A-24 for non-spatial usages? What is the relation “The role of semantic fields in the development between the spatial features of markers and the of postpositions and case markers” of SFB 471 semantic features for the marked entity? at Universitaet Konstanz. 23 24 6
11/16/2012 Languages Surveyed Issues related to Spatial Usages • Indo-Aryan • Fine Grained differences between spatial � Haryani, Nepali, Punjabi, Saraiki, Sindhi, markers Urdu/Hindi � Old Urdu/Hindi, Sanskrit • Polysemy of spatial forms • Indo-Iranian � Balochi, Pashto • Tibeto-Burman � Manipuri • Axial Part (Raza 2011) • Dravidian � Malayalam 25 26 Fine Grained Differences Dynamic vs. Static ablatives in Spatial markers • Ablative of Sindhi, Punjabi, Saraiki etc. Static ( dekhi ) • us=le dilli= dek h i kathmandu=samma 3SG=Erg Delhi= Abl Kathmandu=Loc-till (Sindhi example is presented earlier) baaTo banaa-yo street make.PST ‘He built a street from Delhi to Kathmandu.’ <Nepali> • Dynamic vs. Static Ablative markers • Dynamic ( baaTa ) kud-yo 3SG u dilli= baaTa kathmanDu=samma Delhi= Abl Kathmandu=Loc-to ran-PST ‘He ran from Delhi to Kathmandu.’ <Nepali> 27 28 7

(Raza & Ahmed 2011, Raza 2011) Are these examples of Polysemy or Homonymy? 31 32 8
