Reminder
Many children vomit.
Many have fever.
If you stop at the noun — you cannot diagnose.
The problem
A symptom without modifiers is almost useless. It tells you a
category, not a diagnosis. Vomiting is in hundreds of conditions.
Persistent bilious vomiting in a neonate is an emergency.
The principle
A symptom with correct modifiers becomes diagnostic. Precision is
not pedantry — it is clinical thinking made audible.
The rule
Never present a naked symptom. Always clothe it with modifiers. No
naked nouns in clinical medicine.

The Framework
SOCRATES — the structure that turns nouns into diagnoses
Standard Symptom Characterisation Tool
SOCRATES — Symptom Modifiers Made Systematic
This is the structural tool that operationalises the principle of
adjectives. Every symptom should be characterised using these eight
dimensions. Together, they produce the description that drives
diagnosis.
S
Site
Where exactly? Periumbilical? Right iliac fossa? Localised or
diffuse?
O
Onset
Sudden or gradual? At rest or during exertion? Thunderclap?
C
Character
Colicky, burning, stabbing, dull, aching, throbbing?
R
Radiation
Does it move? To the back, shoulder, groin, jaw?
A
Associations
Vomiting, fever, rash, weight loss, night sweats?
T
Time / Duration
How long? Constant or intermittent? Getting better or worse?
E
Exacerbating / Relieving
What makes it worse? What makes it better? Posture? Food?
Medication?
S
Severity
How bad? Mild, moderate, severe? Does it limit activity?
SOCRATES is not a history-taking checklist — it is an adjective
generator.
Each dimension produces a modifier that narrows your differential.
Students who use it produce precise descriptions. Students who skip it
produce naked nouns.
Examples
Five symptoms — naked vs. precise vs. significance
01
Dengue · Paediatrics
Vomiting
With modifiers
"Persistent vomiting"
persistent
frequency
bilious?
blood-stained?
Diagnostic significance
In dengue, persistent vomiting is a
WHO warning sign — it suggests plasma leakage
risk and indicates the patient needs closer monitoring or
admission. "Vomiting" alone does not.
02
Rheumatology · ARF
Arthritis
Naked noun
"Patient has arthritis."
With modifiers
"Migratory polyarthritis involving large joints."
migratory
poly
large joints
duration
severity
Diagnostic significance
The modified Jones criteria require
migratory polyarthritis of large joints as a
major criterion for acute rheumatic fever. "Arthritis" alone
satisfies nothing. The adjectives are the criterion.
03
General Medicine · Infectious Disease
Fever
With modifiers
"High-grade step-ladder fever for 5 days."
high-grade
step-ladder
duration
intermittent
continuous
low-grade
prolonged
Diagnostic significance
Step-ladder fever pattern raises typhoid. Intermittent fever
raises malaria. Prolonged low-grade fever raises TB or
malignancy.
Fever alone is noise. The pattern is signal.
04
Neurology · Emergency
Headache
With modifiers
"Sudden-onset severe thunderclap headache — worst of life."
thunderclap
sudden onset
worst of life
progressive
early morning
vomiting
Diagnostic significance
Thunderclap headache is the hallmark of
subarachnoid haemorrhage until proven otherwise — a neurological
emergency. Early morning headache with vomiting raises raised
ICP. The modifier determines the urgency.
05
Paediatrics · Emergency
Rash + Lymphadenopathy
Naked noun
"Child has a rash."
"Enlarged lymph nodes."
With modifiers
"Non-blanching petechial rash over lower limbs."
"Non-tender, firm, fixed, generalised lymphadenopathy."
non-blanching
petechial
non-tender
firm
fixed
Diagnostic significance
Non-blanching petechial rash = possible meningococcal disease —
act immediately. Non-tender, firm, fixed
lymphadenopathy raises malignancy. Each adjective is a clinical
decision, not a description.
A non-blanching petechial rash is a safety-critical finding. The
adjectives here do not refine a differential — they trigger an
emergency response regardless of other features. This is where
precision directly saves lives.

The Rule
No naked nouns in clinical medicine.
Always clothe your symptoms with modifiers. The adjective is not
decoration — it is the clinical thinking made visible. A symptom
without a modifier is a missed opportunity to diagnose.
Presentation
What maturity sounds like — the adjective makes the clinician
Compare these two presentations
Same patient — different level of clinical thinking communicated
Immature — do not say this
"Patient has abdominal pain."
Your consultant cannot think with you. No action can be taken. The
information is effectively useless for clinical decision-making.
Mature — say this instead
"Colicky periumbilical abdominal pain for 6 hours, associated with
bilious vomiting, progressively worsening."
Your consultant can now think about obstruction, intussusception,
volvulus. A management plan forms immediately.
The mature presentation does not use more words — it uses more
precise words.
The adjectives are doing clinical work: they narrow differentials,
communicate urgency, and signal that the presenting clinician has
already thought carefully about the symptom.
Final Take-Home Message
"Medicine is not about collecting symptoms.
It is about
characterising them."
Diagnosis depends on precision.
Precision depends on adjectives.
If you are not specific, you cannot be specific in diagnosis.
No naked nouns
SOCRATES every symptom
The adjective is the diagnosis
