Figure 1. Graph: Three Words That Screamed 'I Don't Know What I Did'

A figure caption is a self-contained label, not a paragraph and not a sentence fragment. Get the position, tense, and specificity right or the marker knows you wrote it at 2 a.m. without understanding your own data.

'Figure 3. Results.' Three words. That's the caption. A marker reads it, skips the figure entirely, and docks a mark. Not because the data is wrong—but because the caption tells a reader absolutely nothing about what they're looking at. And yes: table titles go ABOVE the table. Figure captions go BELOW the figure. Get this backwards in a submission and an editor returns it at desk stage. Before anyone reads a single result.

The non-negotiable rule: every caption must be self-contained. A reader should understand the figure from the caption alone—no scrolling back to Methods, no rereading the Results paragraph. This kills the lazy caption dead. ❌ 'Figure 2. Data from our experiment.' → ✅ 'Figure 2. Mean reaction times (ms ± 95% CI) for congruent (blue) and incongruent (red) stimulus trials, collapsed across block (n = 48).' See the difference? The second one tells you what was measured, the uncertainty, the grouping, the sample size. No other sentence in the paper is needed to decode it. If your caption could also caption someone else's figure, it is not a caption. It is wallpaper.

Now the grammar, because this is where the 'obviously written by a non-native speaker' flag goes up. Caption titles use noun phrases, not sentences. No verb. No period at the end. ❌ 'Table 1 shows the results that we obtained from the survey.' → ✅ 'Table 1. Demographic characteristics of respondents by recruitment site (n = 312).' Present tense describes what the figure shows ('Figure 4. Distribution of...' not 'Figure 4. We showed the distribution of...'). Past tense is reserved for the action that produced the data, and only if the Methods section is not elsewhere: 'Figure 5. Tumour volume after 14 days of treatment (measured in...).' Keep it tight. Drop articles before figure/table numbers. 'The effect of temperature on yield' → 'Effect of temperature on yield.' The definite article in a title reads like a sentence, not a label.

The redundancy trap kills more marks than the grammar. ❌ In body text: 'As shown in Figure 4, there was a strong negative correlation between sleep hours and test scores (r = −0.71).' And in the caption: 'Figure 4. Shows the correlation between sleep and test scores.' Now you've written the same thing twice in different broken English. The caption should carry the specifics (r value, confidence interval, what the axes mean). The body text should carry the interpretation. ❌ 'Figure 7. This is a graph of our data.' ✅ 'Figure 7. Scatter plot of log₁₀(CFU) vs. antibiotic concentration (μg/mL) for S. aureus ATCC 25922; dashed line = 80% inhibition threshold.' The reader gets the axes, the organism, the strain, the reference line. Done. No interpretation in the caption. Interpretation belongs in text.

The ESL-specific errors that make a caption scream 'drafted at 3 a.m. after four coffees': missing articles before nouns that need them ('effect of X on Y' needs 'the' in body prose but NOT in the title), 'between A with B' instead of 'between A and B', 'composed of' for figures that are merely 'showing', and the evergreen 'In the figure, we can see that...' ❌ 'Figure 6. The comparison of the data between the groups.' ✅ 'Figure 6. Box-and-whisker comparison of serum IL-6 levels across placebo (n=15) and treatment (n=15) arms at 24 h and 72 h.' Drop 'the comparison of the data.' Name what is being compared, across what, at what time points. Specificity is the grammar that matters most here.

Here is the practical fix. You do not need to agonise over every caption by hand at midnight. Paste the raw, messy, article-riddled draft into easydue and ask it to restructure into a label-style caption with correct noun-phrase grammar. It will not add fake details you did not collect—but it will strip the sentence-fragment energy out and push the phrasing toward the convention your department expects. Then you check: does every axis label, every n, every statistical annotation match what I actually ran? The tool handles the English. You handle the truth.

The caption is not decoration. It is a test of whether you understood the figure you produced. If you cannot write a two-sentence label that names the variable, the group, the statistic, and the unit without reaching for the body text—you did not design the figure. You made a picture. And a picture without a label is not evidence. It is a poster for your own private room. Write the caption first, before you write the body paragraph. That forces clarity. It also forces you to catch the figure that should have been a table, or the 'graph' that is actually three graphs stapled together. Fix the structure before you fix the English.
