Combinations are possible with causal relators and internal changes:
• Maintaining or Upkeep is (cause)(stability)[cause to continue is an alternative here]
• Enhance is (cause)(growth) [Particular forms of this such as moving faster would be captured by more specific compounds]
• Reduce is (cause)(decline). Enlarge is cause increase.
• Include is either (cause to be)(combined) or (cause to be)(contained in) [The ambiguity in the verb ‘include’ is thus dealt with]
• Lubricate is (reduce)(friction) [with oil?]
• Stabilize is (cause to be)(stable).
