Final answer:
The term 'ward' refers to a person, often a minor, who is under the guardianship or care of another individual, as indicated by the context clues from various literary excerpts.
Step-by-step explanation:
The context provided from various literary excerpts gives insight into the meaning of the word ward. In the sentence quoted from Algernon, the use of ward suggests a young person under the guidance or care of another. The term ward generally refers to a person, often a child, who is under the protection and supervision of a guardian. This can be by legal appointment or through the social setting of being in someone's care.
The context from other examples confirms the sense of care and responsibility, as seen in phrases about one’s duties or actions toward others, especially those who are younger or require guidance. Thus, based on the context clues across the various texts, ward can be defined as someone, particularly a minor, who is under the legal guardianship of another individual or in their protective care.
