happy

Compared meaning: feeling pleasure or happiness (adjective).

比较义项：感到愉快、满足或幸福（形容词）。

• happy 本词

  A general, everyday word for feeling pleasure or contentment; it does not imply gratitude for something received, unlike blessed, or an intense, peaceful state, unlike blissful, and is used in almost any context.

  普通、日常的词，表示感到愉快或满足；不像blessed那样暗示因获得某物而心怀感激，也不像blissful那样表示强烈而平静的状态，几乎可用于任何语境。

  He was happy just to sit at home with a cup of tea and a good book.

  他很开心，只是在家里喝杯茶、看本好书就心满意足了。

• blessed

  Suggests happiness caused by receiving something wonderful, such as people's love, luck, or good fortune; carries a warm, grateful tone, common in phrases like 'feel blessed to have...', and is more personal than plain happy.

  表示因获得美好的事物、幸运或他人的关爱而感到幸福，带有温暖、感激的语气，常见于“feel blessed to have...”这样的说法中，比happy更个人化。

  She felt blessed to have such supportive parents by her side.

  她觉得很幸福，身边有这么支持她的父母。

• blissful

  Describes an intense, almost dreamlike happiness combined with calm and peace, typically used for a special moment, place, or state, such as a blissful sleep or a blissful silence, and is stronger than both happy and blessed.

  表示强烈、近乎梦幻般的幸福感，伴随着平静与安宁，通常用于形容某个特别的时刻、地点或状态，如a blissful sleep（幸福的睡眠）、a blissful silence（宁静的沉默），程度比happy和blessed都更强。

  After the long hike, they fell into a blissful sleep under the stars.

  长途徒步之后，他们在星空下进入了幸福安宁的睡眠。

Happy, blessed, and blissful all describe pleasure or happiness. Happy is the general, everyday word for pleasure. Blessed suggests happiness from receiving something wonderful, like love or luck, with a grateful tone. Blissful describes intense happiness with calm. Blessed's religious sense, like 'holy', isn't compared.

这三个词在此义项上都表示“感到愉快、满足或幸福”，但程度和语气不同：happy是最普通、最中性的说法；blessed强调因获得美好事物或他人关爱而心怀感激；blissful则表示强烈、近乎完美的幸福与宁静，语气更强。这里不比较blessed表示“神圣的、受祝福的”这一宗教义项（如the Blessed Virgin）。

Compared meaning: willing to do something (adjective).

比较义项：愿意，乐意做某事（形容词）。

• happy 本词

  Informal and warm, expressing willingness that comes from genuine enthusiasm rather than mere non-refusal; typical of everyday conversation and customer-service offers of help.

  语气随和、口语化，表达的是发自真心的乐意，而不仅仅是不拒绝，常见于日常对话和客户服务中主动提出帮忙的场合。

  The staff were happy to answer any questions we had.

  员工们很乐意回答我们提出的任何问题。

• glad

  Slightly more polite or formal than happy, often used in courteous offers or written requests; still expresses active willingness rather than reluctant agreement.

  比happy稍显礼貌、正式，常用于客气的提议或书面请求中，同样表示积极主动的乐意，而非勉强同意。

  I would be glad to assist you with the paperwork tomorrow.

  我很乐意明天协助你处理这些文件。

• willing

  The most neutral, general-purpose word for willingness, carrying no sense of enthusiasm or reluctance; it can describe minimal or grudging agreement and often appears in negative or concessive clauses.

  是表达愿意这一概念中最中性、最通用的词，不带任何热情或勉强的含义，可以描述最低限度甚至勉强的同意，常出现在否定句或让步句中。

  Few volunteers were willing to work the night shift.

  只有很少的志愿者愿意上夜班。

• disposed

  More formal and abstract, describing a tendency or attitude rather than active eagerness; usually modified by adverbs of degree and suited to institutional or written contexts.

  更为正式、抽象，描述的是一种倾向或态度，而非积极主动的热情，通常由表示程度的副词修饰，适合机构或书面语境。

  The committee seemed favorably disposed toward approving the new proposal.

  委员会似乎倾向于赞成批准这项新提案。

Happy, glad, willing, and disposed all mean willing to do something. Happy is informal, from enthusiasm. Glad is more polite, in courteous offers. Willing is neutral, and can mean reluctant agreement. Disposed is formal, meaning a tendency. 'Joyful' and disposed's 'dispose of' senses aren't compared.

这四个词在表示愿意做某事时含义相近，但正式程度和情感色彩不同：happy和glad语气积极、带有主动乐意的意味，willing最为中性、可涵盖勉强的同意，disposed则更正式、抽象，强调一种倾向。此处不比较happy和glad各自最常用的快乐、高兴义项，也不比较disposed表示处理、处置的其他用法。
