The s udy o discou se g amma eme ged in he la e wen ie h cen u y alongside
he ise o discou se analysis and unc ional linguis ics. One o he mos in luen ial
con ibu ions was Halliday and Hasanʼs Cohesion in English, which es ablished
cohesion as a cen al ca ego y o discou se. They iden i ied i e cohesi e de ices –
e e ence, subs i u ion, ellipsis, conjunc ion, and lexical cohesion – and showed how
hese linguis ic mechanisms c ea e uni y beyond he sen ence le el. Thei wo k emains
he ounda ion o subsequen s udies in discou se g amma .
La e esea ch emphasized he in e ac ion be ween g amma and con ex .
Thompson a gued ha discou se g amma b idges g amma and p agma ics, showing
ha g amma ical choices depend no only on o mal co ec ness bu also on
communica i e pu pose. Ca e and McCa hy highligh ed he idea o “g amma in
use,” s essing ha g amma should be unde s ood dynamically, as speake s and
w i e s employ i in au hen ic discou se. This pe spec i e shi ed a en ion om
abs ac s uc u es o ac ual usage ac oss communica i e se ings.
Bibe e al. ex ended his app oach by analyzing g amma in spoken and w i en
egis e s, demons a ing ha discou se pa e ns a y depending on gen e, mode, and
communica i e con ex . Thei co pus-based esea ch con i med ha cohesion and
cohe ence a e ealized di e en ly in e e yday con e sa ion, academic ex s, and
p o essional communica ion. Mo e ecen s udies u he unde line he impo ance o
cohe ence as a highe -le el o ganizing p inciple, wi hou which cohesi e de ices may

Taken oge he , hese con ibu ions demons a e ha discou se g amma is no

cohesion, cohe ence, and p agma ics, o e ing insigh s in o how g amma ical choices

This s udy is g ounded in a unc ional and discou se-o ien ed app oach o
g amma , pa icula ly d awing on Hallidayʼs Sys emic Func ional Linguis ics (SFL).
Wi hin SFL, g amma is unde s ood no me ely as a se o p esc ip i e ules bu as a
esou ce o making meaning in con ex . Language is iewed as ope a ing h ough
h ee me a unc ions:
1. Idea ional me a unc ion – ep esen ing expe ience and he wo ld;
2. In e pe sonal me a unc ion – enac ing social ela ionships;
3. Tex ual me a unc ion – o ganizing messages in o cohe en ex s.
Discou se g amma is closely ied o he ex ual me a unc ion, which conce ns
how sen ences a e s uc u ed in o la ge , connec ed uni s o communica ion. Cohesion,
in his amewo k, ep esen s he linguis ic de ices ha kni sen ences oge he , while
cohe ence e e s o he highe -le el o ganiza ion o discou se ha ensu es
in e p e abili y and ele ance.
This amewo k also inco po a es cohesion heo y, which emphasizes he ole o
e e ence, ellipsis, subs i u ion, conjunc ion, and lexical cohesion in building ex ual
uni y. Cohesion is unde s ood no in isola ion bu in ela ion o cohe ence: cohesi e
de ices p o ide he o mal links, whe eas cohe ence esul s om con ex ual
in e p e a ion, sha ed knowledge, and logical o ganiza ion o ideas.
Fu he mo e, discou se-p agma ic pe spec i es highligh he communica i e
dimension o g amma . Ca e and McCa hy a gue ha g amma in use e lec s
81
speake in en ions, audience expec a ions, and si ua ional con ex . Simila ly, Bibe e
al. show ha g amma ical choices a y ac oss egis e s, indica ing ha discou se
g amma is sensi i e o communica i e mode and gen e.
By combining sys emic unc ional linguis ics, cohesion heo y, and discou se-
p agma ic app oaches, his s udy adop s an in eg a i e amewo k. I allows o a
nuanced analysis o how cohesion and cohe ence ope a e oge he o shape meaning
ac oss ex ended ex s, whe he spoken o w i en.
Cohesion e e s o he se o g amma ical and lexical mechanisms ha link
sen ences and clauses in o a uni ied whole. I p o ides he su ace connec ions ha
enable discou se o be pe cei ed as con inuous a he han as a sequence o un ela ed
sen ences. As Halliday and Hasan demons a ed, cohesion is achie ed h ough
sys ema ic use o linguis ic de ices ha c ea e seman ic ies ac oss a ex . These ies
guide eade s o lis ene s in in e p e ing in o ma ion and es ablish ela ionships
be ween ideas.
Halliday and Hasan iden i y i e p ima y ypes o cohesion:
1. Re e ence – he use o p onouns, demons a i es, and de ini e a icles o poin
backwa d (anapho ic) o o wa d (ca apho ic) in a ex . Example: Anna bough a book.
She ead i in one day. He e, he p onoun she e e s back o Anna, and i e e s o a
book. Re e ence allows eade s o ack pa icipan s ac oss discou se.
2. Subs i u ion – he eplacemen o one i em wi h ano he o a oid epe i ion.
Example: I need a pen. Do you ha e one? The wo d one subs i u es o pen, educing
edundancy while main aining cohesion.
3. Ellipsis – he omission o an elemen ha can be in e ed om con ex .
Example: Do you wan ea? – Yes, I do [wan ea]. The epea ed elemen is omi ed bu
unde s ood, c ea ing a cohesi e link.
4. Conjunc ion – he use o linking wo ds o signal logical o seman ic ela ions
be ween clauses and sen ences. Example: I was aining, so we s ayed indoo s. The
conjunc ion so exp esses a cause-e ec ela ionship.
5. Lexical cohesion – he use o lexical ela ions such as epe i ion, synonymy,
colloca ion, o seman ic ields o connec ideas. Example: The ca was as . Tha
ehicle could each high speeds. The ela ion be ween ca and ehicle p o ides lexical
con inui y.
These cohesi e de ices ensu e ha discou se unc ions as a meaning ul whole
a he han a s ing o disconnec ed s a emen s. Impo an ly, cohesion ope a es ac oss
bo h spoken and w i en modes. In con e sa ion, e e ence and ellipsis a e pa icula ly
common as speake s economize language, while in w i en discou se, conjunc ions and
lexical cohesion a e o en used o s uc u e a gumen s and na a i es.
In sum, cohesion p o ides he ex ual glue ha holds discou se oge he . Wi hou
cohesi e de ices, communica ion would lack cla i y and con inui y, making
in e p e a ion mo e di icul o he audience. Ye cohesion alone does no gua an ee
o e all ex ual uni y; i mus wo k in andem wi h cohe ence o achie e ull
communica i e e ec i eness.
This s udy has demons a ed ha discou se g amma ex ends he bounda ies o
adi ional sen ence-based g amma by ocusing on he mechanisms ha c ea e

app oach a e he concep s o cohesion and cohe ence, which oge he ensu e ha
discou se is bo h s uc u ally uni ied and seman ically in e p e able. Cohesion p o ides
he su ace-le el links h ough e e ence, subs i u ion, ellipsis, conjunc ion, and lexical

The analysis has shown ha g amma ical choices – such as ense, aspec , oice,
p onoun use, and sen ence complexi y – no only ul ill s uc u al unc ions bu also
con ibu e di ec ly o discou se meaning. These choices a e shaped by communica i e
goals, con ex , and audience expec a ions, illus a ing ha g amma ope a es as a

By in eg a ing cohesion and cohe ence, discou se g amma p o ides aluable

In conclusion, cohesion and cohe ence a e no pe iphe al aspec s o g amma bu
