This image displays a line graph charting the relative frequency of two words over time. The horizontal x-axis represents years, ranging from 1850 to just past 2000, with labels marked every ten years (1850, 1860, 1870, etc.). The vertical y-axis represents percentage values, starting at 0.000000% and increasing in increments of 0.000020%, up to a maximum labeled value of 0.000200%.

A legend at the top center identifies two data series: a blue square corresponds to the word "Aeroplane," and an orange-red square corresponds to the word "Airplane."

The graph shows two distinct trends for these words:

1.  **The Blue Line ("Aeroplane"):** This line remains flat near zero from 1850 until about 1905. Around 1910, it begins a sharp ascent, peaking around the year 1920 at approximately 0.000080%. After this peak, it drops rapidly. There is a smaller, secondary rise around 1945 reaching roughly 0.000060%, followed by a steady decline. From about 1970 onwards, the blue line stays very close to the bottom axis, indicating near-zero usage frequency relative to the scale shown.

2.  **The Orange-Red Line ("Airplane"):** This line also starts flat near zero but begins its rise later than the blue line, around 1915. It climbs slowly until about 1930, after which it rises very steeply. It reaches a massive peak between 1940 and 1945, hitting the highest point on the entire graph at approximately 0.000200% (around 1942). Following this sharp peak, the line drops precipitously back down to around 0.000080% by 1950. From 1960 through 2000, it fluctuates gently between roughly 0.000030% and 0.000040%, remaining consistently higher than the blue line for the remainder of the timeline.

Overall, the chart illustrates a shift in usage where "Aeroplane" was more prevalent in the early 20th century (peaking around 1920), while "Airplane" saw its highest usage during the World War II era and remained the dominant term thereafter.
