*3.8. Definitions*

Of the articles reviewed in our sample, seven provided explicit definitions of urban greenways (see Table 5). To distill the most common themes in these definitions, we removed prepositions, conjunctions, particles, irrelevant verbs (e.g., "defined," "be"), adjectives (e.g., "best," "other"), and adverbs (e.g., "often," "generally"), cited sources, and the terms "urban greenway" and "urban greenways." For consistency, we then edited similar words such as "recreation/recreational," "nature/natural," and "public/public realm" to use the same term. In this vein, we also converted "active travel" to "transportation," as the latter is referring to walking and biking in the context at hand, and active travel (or "active transportation") is synonymous with transportation physical activity in public health literature [43,48,49]. The remaining terms were subsequently fed into a word cloud generator, where the frequency of terms is reflected in font size and configuration (see Figure 5).
